A game that involves one or more men stripping to the nude and somehow stimulating their penises to a solid and strong erection. After doing so one player may then put their hands behing their back and use only their hips to hit small objects (cashews, peanuts, peas, etc.) into a goal (trash can, bucket, girl's mouth, etc.).
Man that was a kick ass game of Umpilo Tim! We sure showed Brian that we know how to shoot those cashews into Suzie's mouth!
