Whilst banging a female you pull it out and preform a bunt
which means slapping her on the face with your dick, yelling bunt, then running. After you yell bunt and run out of the room, your friend has to run in from another door (like a closet or something) and jump onto the bed in a head first dive. Have another one of your friends jump out from underneath the bed and call him safe or out. You can have additional fun by calling him out then getting into an argument about it while the girl sits there nekkid and confused.
Dude we totally pulled a suicide squeeze on Jenny from the block.
