simultaneous ambidextoral coordination

The act of simultaneously wiping each of one's dual buttholes with each hand, separately, at the same time.

This occurs when one has dual dirty buttholes, two hands, and two pieces of toilet paper (preferably clean) and uses one hand to wipe each of the dirty buttholes (one hand per hole, NO SWITCHING!); one hand wiping in a circular motion, the other in straight lines (front to back or side to side, not both), thus achieving simultaneous ambidextoral coordination.
