When one is getting his female partner, from behind, start to slow down, and have one of your buddies sneak in the room and take over (this must be done whith out the girl knowing the switch). You sneak out of the room and walk outside to the window closet to where you were banging her, get her attention, and then she will relize she's not having intercourse with you anymore, and usually flip out.
