Old Man Balls 

Old man balls are when older men's junk becomes one large grapefruit sized, saggy ball. There is no longer the ability to notice two balls, except one large sagging nut.

Example: did you see those old man balls on that guy? Looked like he was sitting with a grapefruit in his pants

Example: while having sex my taint was slapped by his old man balls

Old Man Balls (O.M.B.) 

noun: droopy, wrinkled, testicles that belong to a man 45 years or older. Just the thought of old man balls (more commonly referred to as O.M.B.) is enough to make you shudder with disgust.

Girl 1: "So, how is Paul in bed?"

Girl 2: "Oh man, he was turning me on and all, but then I saw his Old Man Balls (O.M.B.), and I would have needed to do some meth to get on that!"
