The wiggle or dance one makes when trying to release a small amount of poop left to drop to the toilet. This is done to avoid wiping the excess poop and decrease the chance of said turd to be spread on hand. Does not need to be done when one has diarrhea.
Person 1: Man what took you so long in the bathroom, i thought something went wrong
Person 2: I was doing the fucking Crapper Can-Can. Did not want to get shit on my hand. That little sucker wouldn't budge.
Person 1: Too much info. Why am I friends with you?...
