A group dance, generally used as a hazing activity. Put one thumb in your mouth and the other in the asshole of the person in front of you. Everybody does this so that it forms a loop. You proceed to dance around in a circle. Should anyone's thumb become dislodged from the ass of the person in front of them, they must switch thumbs.
