Asscresting is a facet of foreplay that involves snuggily placing the erect penis in the middle of the girls(or guys, asscresting is applicable to sexual orientations of all kinds) asscheeks and sliding or rotating in any desired direction. It is essentially grinding without pants on. Highly convenient and surprisingly pleasurable, asscresting is on the rise as an act of foreplay and i encourage anyone interested to experiment. Don't knock it till you try it. dicks.

"Yea she wasn't ready for sex so we just asscrested, it was chill."

Ass Crust 

A derogatory term used to describe anyone who pisses you off. Derived from the leftover pieces of shit left in your ass after the umpteenth swipe.

Not to be confused with asshat.
