“Cache” (pronounced like “cash”) is a small, hidden storage spot—either on your computer, phone, or even in real life—where frequently used things are kept so they can be reached faster the next time you need them.

People talk about cache all the time when apps feel slow: “Clear your browser cache and reload the page” or “My game keeps a cache of the last ten levels so it starts quicker.” It’s also why your favorite coffee shop might pre-grind beans into a small bin behind the counter—an everyday “cache” so the barista can serve your latte faster.

Meaning & Usage Examples

• Web browser cache: Chrome, Safari, or Firefox save images and files so pages load faster on your next visit.
• App cache: Instagram stores thumbnails locally so your feed scrolls smoothly.
• Hardware cache: A tiny, ultra-fast memory on your phone’s chip that keeps your most-used apps ready to open instantly.

Common Contexts

Tech support: “Delete the cache if the site looks broken.”
Smartphones: “Low storage? Clear cached data to free up space.”
Gaming: “The console builds a shader cache to cut loading times.”

Is cache the same as cookies?

No. Cookies are small bits of data about you (like login info), while cache is copies of actual files and images to speed things up.

Will clearing cache delete my photos or passwords?

Clearing cache only removes temporary files; your photos, passwords, and personal data stay safe.

How often should I clear my cache?

Only when an app or site is acting weird or you’re running low on storage—otherwise, it just helps things run faster.

“Maximum number of attempts” on TikTok means the app only lets you try a certain action—like logging in, entering a code, or following someone—a set number of times in a short period. Once you hit that limit, TikTok temporarily blocks you from trying again.

You might see it when you forget your password and try to reset it too many times, or when you tap “Follow” on lots of accounts quickly and TikTok thinks you’re spamming. After the limit, you just wait a few minutes or hours before the app lets you retry.

Meaning & Usage Examples

• Login code: Entering the wrong SMS code five times in a row.
• Following spree: Tapping “Follow” on 50 accounts within one minute.
• Live gifting: Sending virtual gifts repeatedly until the counter says “Maximum number of attempts reached.”

Common Use Context

Most users bump into this when they’re in a rush—forgetting passwords, bulk-following after a viral shoutout, or spam-liking during a live stream. TikTok’s bot-detection kicks in, pauses the action, and the message pops up to protect everyone’s experience.

How long do I have to wait?

Usually between 5 minutes and 24 hours, depending on the action.

Can I bypass the limit?

No. The block is automatic; just wait and the feature unlocks itself.

“Invalid Parameters” on TikTok is a short way of saying the app didn’t understand the request you just sent. It’s like when you give someone the wrong address—they can’t find the place. The app expected one kind of info, got something else, and throws this message to stop things from breaking.

Most people bump into it when they tap a link, try to open a profile, or hit “Follow” and the page freezes. You might be using an old video URL, or the creator changed their username, or TikTok just hiccuped. Closing the app, checking the link, or refreshing the page usually clears it up.

Meaning & Usage Examples

Think of it as a polite red flag. Example: you open a DM that says “Check this video!” but the clip was deleted. TikTok shows “Invalid Parameters” instead of a broken page. Another time you might see it is when you copy-paste a profile link and leave off the last letter by mistake.

Context / Common Use

You’ll mainly spot it when sharing or opening links, scanning QR codes, or switching between the mobile app and browser. It’s not a ban, just a mismatch between what TikTok expects and what it receives.

Does this mean my account is suspended?

No. It’s a technical glitch, not a punishment. Log out and back in or restart the app and you’re usually fine.

How do I fix it fast?

Copy the link again from the original source, make sure nothing’s cut off, and open it in the latest version of the TikTok app.

“Dom” is a short, friendly way to say “Dominic,” a common first name. In everyday slang, it can also mean “dominant” when people talk about personality or relationship roles.

Friends call their buddy Dom instead of Dominic. Online, you might see “Dom looking for a sub” on dating apps—here it just means someone who likes to take the lead. In gaming chats, a loud player may joke, “Okay, let Dom handle the boss fight,” meaning the strongest or most confident teammate.

Meaning & Usage Examples

• Name: “Dom’s bringing snacks to the party.”
• Dominant role: “She’s a Dom in their dynamic.”
• Gaming: “Dom, take the shot!”

Common Context

Mostly casual: nicknames among friends, dating profiles, or team games. Rare in formal writing.

Is Dom short for anything else?

Almost always Dominic. Very rarely, people use it for “domain” in tech talk, but that’s uncommon.

Does Dom always mean dominant?

No—only in specific dating or lifestyle contexts. Most of the time it’s just a guy’s name.

“Alt Slang” is short for “alternative slang.” It’s a fresh, often edgy twist on everyday words or phrases that’s used mainly by younger crowds online or in texts. Think of it as slang for slang—new ways to say old things, sometimes drawn from memes, gaming, niche fandoms, or fast-moving social media trends.

People drop alt slang into tweets, TikTok comments, Discord chats, or even in-person jokes to sound funnier, cooler, or part of the “in” group. One friend might say, “That track is fire,” and the other replies, “Big slay,” both meaning the same thing but the second uses alt slang. It’s quick, playful, and changes fast—today’s “rizz” could be tomorrow’s “aura.”

Meaning & Usage Examples

Alt slang keeps shifting, but here are three simple, current examples:

• “Bet” – A cool way to say “okay” or “sure.” Example: “Movie at 8?” — “Bet.”
• “NPC” – Used to call someone boring or acting like a background character. Example: “He just repeats whatever’s trending—total NPC.”
• “It’s giving” – Short for “it’s giving off vibes.” Example: “Your outfit? It’s giving main character.”

Context / Common Use

You’ll spot alt slang on TikTok captions, Twitch chats, and group texts. If a word feels brand-new and a bit meme-y, it’s probably alt slang. Don’t worry about mastering every term—just recognize the vibe and you’ll catch on fast.

Is alt slang the same as internet slang?

They overlap, but alt slang is the newest layer—often shorter, more ironic, and born from memes or fandoms.

How quickly does alt slang change?

Very. A phrase can blow up in a week and feel old in a month, so don’t stress about keeping a perfect glossary.

“Shell slang” is internet shorthand for short, cryptic phrases people drop in chat apps like WhatsApp, X, or Discord when they want to sound cool or stay low-key. It’s a mash-up of code words, emojis, and acronyms that outsiders usually don’t catch at first glance.

In real life, you’ll see teens or gamers fire off a shell slang message like “gm” for “good morning,” “ngl” for “not gonna lie,” or a simple skull emoji to say “that was funny.” It keeps the chat moving fast and lets friends feel in-the-know without spelling everything out.

Meaning & Usage Examples

• “lmk” = let me know
• “iykyk” = if you know, you know
• “w” = win / dub
Drop these in a WhatsApp group or on X and everyone instantly gets the vibe.

Context / Common Use

Shell slang shows up most in rapid-fire chats, gaming lobbies, or quick X replies. It’s rarely used in emails or formal posts; it’s built for speed and insider flair.

Is shell slang the same as Gen Z slang?

Most overlap, but shell slang is extra short—often just a few letters or one emoji—while Gen Z slang can be full phrases like “no cap.”

Can I use shell slang at work?

Only with coworkers who already use it; otherwise it can look unprofessional or confusing.

“Tube slang” is just a casual way people talk about the London Underground. It’s the nickname Londoners give to the subway system, the same way New Yorkers call theirs “the subway” or Parisians call theirs “the Metro.”

In everyday life, you’ll hear locals say things like “Take the Tube to Covent Garden,” or “I’m on the Tube—signal’s awful down here.” Tourists quickly pick it up because every map and sign still spells out “London Underground,” but everyone around them keeps saying “Tube.” It’s short, friendly, and feels like part of the city’s lingo.

Meaning & Usage Examples

• “I missed the last Tube.” (I missed the final train.)
• “Which Tube line goes to Camden?” (Which subway route?)
• “The Tube strike is tomorrow.” (The Underground workers are striking.)

Context / Common Use

People use “Tube” in texts, on social media, and in spoken chat. You’ll see hashtags like #TubeStrike or hear “Mind the Tube gap” jokes. It’s so common that even the official Transport for London app uses the word “Tube” in its menu.

Is “Tube” only for London?

Yes. Outside London, Brits just say “metro,” “subway,” or the city’s own system name, like “Glasgow Subway.”

Do tourists sound odd if they say “subway” instead?

Not really—people understand—but saying “Tube” helps you blend in and locals appreciate it.

On TikTok, “cache” is the temporary storage of small files—like videos you’ve watched, thumbnails, and profile pictures—saved on your phone so the app can load faster next time. It’s like a quick-access drawer the app keeps to avoid re-downloading the same stuff over and over.

People clear the TikTok cache when the app feels sluggish, videos keep buffering, or the phone storage warning pops up. You tap Profile → Menu → Settings and privacy → Clear cache, and TikTok dumps the saved files. Nothing personal (likes, drafts, or followers) gets deleted; it just frees up space and often makes scrolling smoother again.

Meaning & Usage Examples

Meaning: A hidden stash of temporary data that speeds up the app.
Example: “My FYP was stuck on the same three videos. Cleared the cache and everything refreshed instantly.”

Context / Common Use

Most users only think about the cache when TikTok starts freezing or their phone storage is almost full. It’s the first fix people try before uninstalling or restarting the phone.

Does clearing the cache delete my drafts or likes?

No. Only temporary files are removed; your drafts, likes, and account stay exactly the same.

How often should I clear the cache on TikTok?

Whenever the app feels slow or you get a low-storage alert—usually once every few weeks is enough.

“Video under review” on TikTok means the app is taking an extra look at your clip before it can go public. The video is hidden from everyone except you and the moderation team while they check it for possible rule-breaking content.

In real life, creators see this message right after they hit “Post.” It pops up under the video thumbnail and stays there for minutes or even hours. People often refresh their profile or message friends asking, “Is it still under review?” while waiting. Sometimes the video gets cleared and goes live; other times it’s quietly removed and the creator gets a notice.

Meaning & Usage Examples

When a clip shows “Video under review,” it’s like being in a short holding room. Examples:
– You upload a dance clip and immediately see “Video under review” instead of your usual For You feed boost.
– A cooking tutorial gets flagged for a knife trick and sits under review for two hours before it’s allowed to publish.

Context / Common Use

TikTok’s automatic systems scan every upload for violence, nudity, misinformation, or copyrighted music. If the algorithm spots something borderline, the video is queued for a human check. This happens most often with new accounts, trending sounds, or clips that use sensitive keywords.

How long does “Video under review” last?

Usually a few minutes to a couple of hours. If it takes longer, the video is likely under detailed human review.

Can I speed up the review?

No. Refreshing or reposting the same clip usually just puts it back at the end of the line.

“12” is simply the number that comes after 11 and before 13. It stands for a dozen, or 12 units of anything—hours on a clock, months in a year, eggs in a carton.

People use “12” all the time in everyday talk. They’ll say, “See you at 12,” meaning noon. Or, “Grab a 12-pack,” referring to a box of 12 cans. Kids learn to count to 12 early because it shows up on wall clocks, calendars, and sports jerseys.

Meaning & Usage Examples

• Time: “Lunch starts at 12.”
• Quantity: “I need a 12 of soda.”
• Sports: “He wears number 12 on his jersey.”

Context / Common Use

In the U.S., “12” also doubles as quick slang for police (from the TV show “Adam-12”). You might hear, “The 12 just rolled up,” in casual street talk.

What does “12” mean in texting?

It usually just means the number 12, but some use it to say “police are here.”

Is 12 noon AM or PM?

12 noon is 12:00 PM. Midnight is 12:00 AM.
