When you shave someone's head, take a hollowed out melon, rub shit on the outside and jiz on the inside then stick it on the bald guy's head shouting "Crank that arnold!" Usually occurs between gay men in prison or an unconcious guy and arnold g.
Arny-'Yo man, I'm bored'
Bob-'Let's crank dat arnold'
Arny-'That's cool, like coolade'
