somebody who has more rolls than any sumo wrestler alive and leaves a trail of fat juice while walking down a path after eating and eating more food then one can think of. to be at this stage, one must complete 4 courses of all fast food chains for 3 months straight, tubs of miracle whip, and chocolate dipped everything.
no exercise or concentration needed.
