More of an ongoing party game best played at college parties. Split up the quarters so that nobody at the party has more than one, but everyone doesnt have one. Guests can use their own (this works best). You walk around and drop a quarter in someones cup when they are not paying attention, once this is done they must chug the contents of the cup. Anyone with a quarter may drop a quarter in anyones cup. It is best to find someone who just visited the keg and has a full cup. As the night wears on, people become paranoid and things start geting crazy as drink holders get larger.
