Crisp ass
A perfect ass.
Damn, I just wanna take a bite out of that crisp ass!
ass crisps
When one does not whipe properly and leaves shit all over their asshole and allows it to dry. Friction then causes a flaking of the dried poo and accumulates in ones underwear, often in a fine powder.
After john found out he had ass crisps he sprinkled them all over my chocolate cake.
