When someone (typically a guy) drinks 2 litres of coffee and a full bottle of laxatives. Once the shit has been brewing for long enough you shit it out in a straight line that’s around the same width as you(if you don’t have enough, drink more coffee and take more laxatives). After the “Water slide” has formed you take another person and have them at the other side of the “slide” in “doggystyle”. After all that is set up you run, slide, and aim your head for there asshole. If everything went right you should pop your head into them.

Bro, I was with this chick last night and we were doing anal, when out of nowhere I gave her a Mud Slide!
