Paddleball 

When a man is getting sucked off ,preferably by a female, and the playing with the balls gets vigorous to the point she's smacking them with her hand.

My nuts hurt from the girl playing paddleball.

paddleball 

when in the 69 position the man vigorously bounces his balls off of the woman's forehead, like a small child playing with a paddleball.

She didn't like it when I paddleballed here when she was slobbing my knob.

Paddleballing 

When a man repeatedly thrusts his groin into the air, causing his package to bounce out and come back. Similar to how a paddleball returns to the paddle, after being swung all the way out.

Male Stripper: *faces audience and begins thrusting out*

Viewer1: "Oh shit, dude. He's paddleballing!"

Viewer2: "OH MY GOD, LOOK AT IT GO!"

Viewer1: "SO HYPNOTIC!"

Saddleballs 

When your balls are so big you have to walk like you just got off of a horse.

“That guy is walking like he just got off a horse. He definitely has saddleballs!”
