Get the Hammer armmug. When a young female puts their hand on their hip with their elbow bent at a 90-degree angle. Inspired by prom pictures and attempts to make arms look tiny.
Katherine had such bad Prom Arm in all of the pictures from last night. I think she was trying to impress Sean by tricking him into thinking she has tiny arms.

Get the Golden Armsmug. The outstretched arm of the raver or partygoer who's dance moves are mainly reflected in the up and down motion of said outstretched arm. Over exertion of the rave arm may lead to a larger and more muscular appearance indicating that it might in fact be a wank arm.
