beat the clock

A horrific "game," where participants (typically adolescents with permanent erections and nothing better to do) sit together (often in formation around a focus, say a tv or computer screen) watching porn, and masturbating furiously. The criteria for "winning"/losing vary from game to game, but there can be unpleasant consequences for he who shoots before/after everyone else. Most often, however, whoever fails to shoot before the allotted time has elapsed is said to have lost. See: bukkake
