Pinballing

When you grab someone's testicles and stretch them with such force that they snap back to their body, it’s like the action of a pinball machine launching its ball. The sensation is akin to pulling a spring to its limit, and then releasing it, resulting in an immediate and powerful recoil as the testicles are violently propelled back to their original position. The sudden and intense motion creates a jarring, painful impact that reverberates throughout the area, leaving the individual with a sharp and lingering discomfort.

I started pinballing jimmy so hard his balls went right back inside him.
