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

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.
