killed the cow

Dropping some major ass. This type of fart is especially vile-smelling. As it seeps through the room its victims snap their heads back, as if slapped in the face.

Damn, man, shit. Whoever killed the cow had better get to the clinic, cause that aint right.

A.L.

Ass Leak. A cousin of the fart, this is a condition that occurs when your butt slowly leaks a continuous stream of gas.

Damn, Nick killed the cow!
I can't help it, I have A.L.
