A variation in the hand-ball rules. This rule stipifies that if a player can keep the ball in play buy thrusting their groin (male or female, this rule does not discriminate) at the ball resulting in that player remaining "in" and the game will continue as normal. Also, if a player can manage to serve "Groin Ball" style the game will end and all the players must carry the server on their shoulders through the massing crowd of amazed on lookers.
A player mishits a ball into the air. In an amazing feat of atheleticism the player (Mario) manages to bat the ball into his opposing player's court by thrusting his groin at the airborne ball.

A groin blaster is when you have an erection, and then you pull your legs together towards your groin really fast. This causes a painful rush of blood to the penis.
