A sexual position in which the woman does a handstand. The man then sticks his magical balls into her vagina (Literally sticks em in) and she jerks him off (or if she's lazy, he can jerk himself off). This is repeated until the man cums and then he sits down hard, thus slamming the bitch's head against the floor.
Sally: Oh my god, Cindy, what happened to your head?

Sally: Oh shit, pwned nigga!
