mouth breathing

Bypassing the nose

Mouth breathing is breathing through the mouth rather than the nose, often due to nasal congestion or habit.

The term has become internet slang for stupidity or social obliviousness—the image of someone slack-jawed and vacant: The comments section was full of mouth breathers.

As an adjective, mouth-breathing modifies nouns directly: mouth-breathing idiots.
