It's when you take a massive dump over your
towel. You wait for it to become dry and
crusty so you can wipe it off the towel so you can sculpt it into a anime body
pillow.
Mom: Niggato what are you doing in there?
Niggato: I'm masterbating to my towel
feces!
Don't look!
Mom: What?!
Niggato: you'll never catch me
Narrator: Niggato runs away from his room, fleeing with his
feces body pillow
