nutflap

The leftover skin of the scrotum after a man gets his testicles removed, so the "flap" of skin from the "nut"sack.

"They couldn't save his balls because of the impact of all those fish, so they had to settle with the nutflap."

Nutslapper

A tremendously long bowl movement which, upon evacuating the rectum, falls forward, slapping the back of the scrotum before falling into the toilet.
