Backpack Flipping

The art of having ones backpack flipped inside out. In contrary to the popular term "Nuggeting". When a backpack is flipped where is the nugget. I looked all over for it and I could not find it anywhere. I searched inside of the backpack and I searched outside. I was really hoping to find a nugget cause I was pretty hungry at the time.

I take part in Backpack Flipping
