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

"So how did Jim's surgery go?"
"They couldn't save his balls because of the impact of all those fish, so they had to settle with the nutflap."

Scott: “Oh I’ve got nutflap as the disease my doctor diagnosed me with it”
Jenson: “good you but face”
