This simple and comical Men's Red Beer Pong Cup and Ball Costume will spread some laughs throughout your party. The standard size set includes a large red cup with straps a white blow up ball. Once limited to college campuses, beer pong is now a national - and even international - sensation. On the Tonight Show with Jimmy Fallon, the host has played beer pong several times including games against Diane Keaton and Nina Dobrev. In the game, each side arranges 10 cups into a triangle and partially fills each one with beer. Each player throws a ball across a table and aims for the other player's cups. If the ball gets in, the other player has to drink the beer. The game is won when one player gets a ball in each of the other player's cups. If you are going to play beer pong, call a cab or make sure you have a designated driver.
