After nuggeting a bag by turning it inside out, but before you zip it up, you take a poopy in it. Then you complete the nugget by zipping up the bag. A variation of this would be to take the crap in a ziplock bag and then insert it into the bag. You may also urinate on the outside of a completely nuggeted bag.
I dirty nuggeted Marc and threw it in the woods.
