A term used to describe a position of sexual intercourse.
An assfuck is achieved when a male inserts his penis into someone's ass, or anus. This usually causes bleeding in the person receiving the assfuck, but immense pleasure and some penis shrinkage in the person giving the assfuck.

One who fucks asses. There is an unspoken implication that said "assfucker" is a male who prefers fucking male asses, i.e. who is gay.
