F.U.C.R.
The fatty part on top of a guy’s junk. It’s like a belly button but for the upper part of your junk.
My brother’s F. U. C. R. is so big it’s making his pants look like they’re in pain.
He tried to hide his F. U. C. R. under a shirt but it just came out like a confused dog.
At the beach, his F. U. C. R. got so much attention it started its own fan club.
