A prank usually done at parties where one person stands up with just his boxers on, having his ass in front of someones face. While this is happening another person punches that person in the stomach. when that person goes to withdraw their air again, their is an ass in their face. Naturally, they will suck up all of your ass gas and cough until they puke.
