The act of taking a friend's backpack, removing everything, turning the backpack inside out, refilling the backpack, and ziptying it shut. Ziptying the backpack prevents an easy fix to the situation. If done properly and near the end of class, the victim will have to carry their "Nugget" in their arms as they walk down the hall. This can be referred to as the "Nugget Walk of Shame."
I went on a Nuggetting spree fifth period, I got like five!
