“Mouth breather” is a phrase used to describe a person who usually breathes through their mouth instead of their nose. It can be used in a literal way, especially when someone has trouble breathing through the nose, or as an insult to mean someone is seen as slow, clueless, or not very smart.
In everyday life, people usually use it to describe breathing habits, especially in children or when someone is sick, congested, or sleeping. But in casual speech, it is often used as a rude insult, so the meaning depends on the situation and tone.
