beer butt

Like a beer belly, beer butt is the result of consistently drinking large quantities of beer. Beer butts are large and often saggy and/or jiggly.

Mer: Have you seen the beer belly on Ben?

Cassie: Ha ha, yeah, but that's nothing compared to his beer butt!

Mer: Oh yeah, that thing is HUGE.

beer butt

The last swig of a beer left in a bottle or glass, it's butt.

Almost all of the beer had been drunk, what remained was the beer butt.

butt beer

Beer filtered through the ass crack. (Hairier the better of course.)

The frat always chose to filter butt beer for the pledges through Pat's unusually hairy ass crack.
