Nadruff
Nadruff is the crusted mess left when your balls rub against your underwear like a dirty sock in a sock drawer. It’s basically a mix of skin flake, cum, pee, and whatever else your junk decided to leave behind.
My nadruff looks like a science experiment gone wrong. I’m 100% sure my pants are now a second skin.
I woke up to a nadruff explosion. My boxers are now a permanent part of my body.
My nadruff is so bad, my dog ran away from me.
