The premise is that of a bachelor having his final fling with a room full of inexplicably nude women. The equally unclothed bachelor is propelled repeatedly into the room of women by a "Spanish Fly" used as the player's paddle. When entering the fray, the bachelor's exaggerated and pixelated penis is seen to be erect. When he returns from having collided with (and presumably "scored" with) a woman or after hitting the opposing wall, his penis sags. It returns to erect when the bachelor is successfully set moving again toward the left.
A second version of the game, titled Bachelorette Party, also exists. It has no difference in gameplay, but has the game sprites reversed: The player now uses his or her paddle to bounce a naked woman toward naked men. It was reviewed by the Nerd in the episode Atari Porn.
