Describes the physical position of someone who is gurned
up to their tits.
Put your arms straight out in front of yourself, then bend your elbows so that your foreams are at a right angle to your upper arms, and parrallel to your body. Fully extend your fingers, then bend your wrists down, to form a sort of 'M' shape with your forearms and hands.
When accompanied by rolling eyes, a swinging underbitten jaw, and low-soft groaning noises, can be highly amusing.
