Paddleballing
A man wiggles his junk up and down like a crazy person, making his nuts bounce like a ping pong ball off a paddle. It's the worst kind of dance, and it's happening in your head.
My dad was paddleballing so hard, I thought he was trying to knock out the neighbor.
He was paddleballing in the gym, and the weights were jealous.
During the Zoom call, my uncle was paddleballing like it was a live concert.
