This is a prank 2 people play on one guy. One guy stands in back of the victim and one stands in front. The guy in back starts by pokeing the victim in the bum hole, the victims response is to squeeze his butt cheeks togeather, which exposes his balls from the front. The person in front now gently whoops the victim's balls, causing great pain. The whole jist of it is to hurt the dude's nuts in a funny way.
