When you're having anal sex and the person on the receiving end bleeds and shits on you're dick while you cum.
Chris: Dude this one time Sally and I were doing anal and she bled out of her asshole and she fudged my stick dude once I came.

Josh: dude no way she gave you a tuff mudder!!!!!!!!

Get the Tuff Mudder mug.
Someone who shits right after someone else, and can feel the heat on the seat.
My pal Dave had to go so badly he pulled a real tuff mudder at the bar. What a champ.
