Two couples were competing for a prize. The younger couple lost when it took the girl 3 minutes to get her guy to cum while the older girl only took 2:45 to get her guy to cum and she beat the clock

The act of seeing a Girls Gone Wild commercial come on the TV, preceding to gain erection, and reaching ejaculation prior to the end of the commercial.
Last night I couldn't sleep so I was watching TV and a new GGW commercial came on, I beat the clock.

Beat the clock is a great, although difficult game to play. When fucking a girl from behind, you pull out a knife and stab the girl. You then have to fuck her hard enough to "beat the clock" and cum before she dies.
I was playing beat the clock with some whore last night but she died before I could nut. Now I've got mad blue balls.

engaging in sexual intercourse for a period of time, then promptly slashing her throat while attempting to ejaculate before her heart stops. remember..youre not a necrophiliac if you finish before her heart ceases to beat.

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.
