Any human being that breathes in and out through their mouths, often engaging in idiotic and useless activity. An affinity for sexually crude humour generally accompanies.

Get the mouth-breathermug. 1. A moron from a low social caste. Picture someone with a sunken forehead, low hairline, and prominent chin.
2. A guy who goes to the gym seven days a week, probably does steroids, and has a body that looks like a comic-book character. He might be 5'4" but his arms and shoulders are so overbuilt that he looks ridiculous.

Get the mouth-breathermug. Someone who's been in too many fistfights and thus has had the ability to breathe through the nose beaten out of him. The usual implication is that the ability to use the brain has also been beaten out of him.
My bookie sent a mouth breather to collect for him, but when the goon tried to get me to head to the ATM with him I escaped for the moment by saying his shoe was untied.
