The Jesus Lizard - Mouth Breather (Live 4-29-1991 DC)
(by BongHitBrian)

“I leave my home, I leave for a couple weeks / I leave my home, I leave it in the care of a friend / Don’t get me wrong, he’s a nice guy, I like him just fine / But he is a mouth breather.”

Mouth Breather: A person of inferior intellect that lacks the faculties to recognize he is breathing heavily through his drooping open mouth.
