A lethal disease that develops from eating too much ass. The inside of the lungs becomes coated in a brown, shit like substance. There is no known cure.
Poor Andre. After years of eating his wife's ass, the brown lung finally caught up to him. His funeral is Saturday.

Get the Brown Lung mug.The act of self inhaling smoke into one's butthole, similar to a butt chug,and shotgunning it into another individuals mouth.
Dude, we tried the brown-eyed lung this morning before work, she sucked down a cigarette with here anus and then blew it in my mouth, shitting on my face by accident.
