butt pepsi

Extreme liquid diarrhea. Sometimes carbonated.

Bro, I just had an entire case of butt pepsi.

Butt Pepsi

Literally tastes like ass. Not at all as good as Coca Cola that dripped off of someone's taint.

That butt Pepsi tastes a little fecal. I'd much rather have some other form of questionable Cola. Perhaps one of the tainted kind.
