The act of plowing and destroying a vagina during intercourse. This is when you plow your girlfriend into the floor, possibly causing some internal bleeding and injury. This usually feels amazing for the guy, but can severely hurt the girl. This is an aggressive form of intercourse and should only be used by someone like Clifford.
