An injury sustained during sport activity whereby another player fouls the ball holder by yanking their penis in an effort to make them drop the ball.

The injury could also be incurred by allowing a midget to swing from the flaccid penis like they are Tarzan.
He got a groin strain when a player from the other team gave him a willy tug! It will take weeks for that groin strain to heal itself back together internally!
