When two dudes are fucking one woman and the scrotum from one of either bounce, graze, slap, knock, tag, etc., against the other pokers scrotum.
Hey man! Your balls are like wingnuts bouncing on a drum. When we were nailing her your balls and my balls were knocking hard and fast like a mad mother fucker pounding on a cheater's panic room. Too much testicle tag for me. I'm sorry, but your balls have got to go.
