butt scuttling
when two people race each other around a defined object. the participants race by sitting on their butts, using only their feet to drag themselves forward.
when i walked in, i saw two guys sliding around on their butts as if they had worms. turns out they were actually "butt scuttling".
Scuttle Butt
One whose butt is small and scuttle is very large.
That Jessica girl sure is a Scuttle Butt, I can hardly see her butt under all that scuttle!
