A shit taken after a night of hard drinking that is particularly difficult to deal with. Unlike the traditional morning-after shit (which is an even-flow of black, smooth tar), the Tough Mudder’s consistency is that of mud mixed with clumps of ribs and chicken wings that act as grappling hooks inside the anus. Putting a foot up on the tub and screaming as though in labor is a typical method of dealing with this difficult shit. Not to be confused with the Labatt Splats.
"I had a Tough Mudder this morning that nearly killed me. I was on the can for a good hour AND I got a nose-bleed while pushing..."
