Get the assfuckmug. 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.
