Two people take off all their clothes. A belt (or something gross) is tied around their necks like a noose. They wrestle on all fours and try to run away from each other. The first one to cross the middle line gets their ass kicked.
My cousin tried to run away, but his butt slipped and he face-planted.
The belt was a used shoelace and it stank like a fart factory.
My uncle said it was the worst thing he ever saw, and he once ate a sock.
