An agressive shit-shake in the toilet after going on a McBinge. Will generally have the bathroom smelling of a Happy Meal when finished.
*Group of girls head to the ladies room to touch up their make-up*

First girl: Omg it smells like McDonald's in here!
Second girl: Sorry, I took a McShit a few minutes ago...
Third girl: Ew!!... disgusting.
