speed bag balls 

The feeling you get when you have passionate sex and your balls hurt from smacking into your partner. They hit off them like a person hits a speed bag in boxing.

Getting your ass kicked, beaten, or destroyed in a manner that makes you give up. Especially in games.

Damn Andy, your ball speedbag got used by your girlfriend in that COD match.
