When someone, usually over the age of 85, rides a bicycle and gets their nutsack stuck in the bicycle chain. It usually results in a painful yet hilarious removal of the scrotal skin from the oiled bike chain.
"Jack, did you see grandpa? Hes down the corner yelling help my nutsacks in the bike chain!" Looks like grandpa had an Athletic Ballsnatcher.
