A large amount of flesh and fat around the male pelvic region. It occurs to obese men and is more pronounced when tight fitting trousers or sweats are worn.

Those tight fitting pants Bill is wearing really highlights his Nut Fat. It looks like he's trying to smuggle a bosa ball in his pants.

Busting a Mighty Fat Nut 

v. Ejaculating in a satisfying or otherwise noteworthy manner, especially if an unusually high volume of semen was produced. If the nut was busted under embarrassing and/or hilarious circumstances, chances are it was a mighty fat nut.

I was jerking off in my room, and right as I was about to finish my mom called me down for dinner, and I yelled "coming!", then started laughing really hard at the double-entendre, but the laughter made me double over and I ended up busting a mighty fat nut all over my brand-new polo shirt.
