A legendary condition marked by the development of two opposable cocks to the right and left of the original one. The original cock remains stationary, but the other two can manuver in a multitude of ways. Only two men are known to have this condition. One goes my the name of Jim, the other is is black half-brother Koss. (note that Koss only possesses the Hydra-dick one day out of the week)
