While the victim is sleeping, preferably face up, the person performing the task begins to masturbate. Just before ejaculation, mount the victim such that the sperm will land on the victim's lips, and punch them dead in the face. Right when they wake up, shoot a load in their face or mouth, jump off and yell, "I GOT YA BITCH!," then run out of the room and get in a car and drive away. Name inspired by the Donkey Punch
