mouth breathers

Open-jawed air inhalers

Mouth breathers literally describes people who breathe through their mouths rather than their noses, often due to congestion or habit.

The phrase has become a popular insult suggesting someone is stupid, slack-jawed, or socially oblivious: The comments section is full of mouth breathers.

The implication is of someone too dim to perform a basic bodily function correctly.
