When two gentlemen, usually heterosexual and inebriated, engage in a competition to see which of the two gentlemen can sustain an errection the longest, with a partially hollowed out melon over their penises.

The first to have their melon drop to the floor is the loser.
George and Alfed covered their throbbing hard cocks with the hollowed out remains of a delcious watermelon, having just agreed to a melon on.
Alfred, weak from the 13 cocksucking cowboy shots he had recently downed, lasted a meer 13 seconds before the watermelon dropped to the floor in what can only described as a bloody mess. George, delighted at his new found glory, shoved his cock up Alfreds arse, and they both agreed they were all winners in the end.
