Tritesticle

When yo gurl so lit that she pushes your penis inside the ball sack, the resulting bulge moves the testies to the side creating a triangulare shaped sack with 3 bulges. The resulting flesh package is referred to as a tritesticle.

You she was about to give me head but she was pissed I didn’t do the dishes so she game me a tritesticle instead.
