The act of using watery feces to humiliate another individual in any way whatsoever. Also an act of morbid affection.
We all watched in horror as Danielle Donatello vandalized Xander Zimmalina's Shitty Times Ten(Chevrolet S-10) by putting her watery feces all over it. She later explained that she had just performed the infamous Mississippi Mudslide. She also added that this is also an act of morbid affection. We were totally shocked and genuinely afraid. We then proceeded to back away slowly while carefully keeping her in our line of vision. Before finally sprinting to safety one of us told Danielle to "look over there". Upon success of this classic diversionary technique, we found safety in a nearby alley. Breathing heavily we all wondered if one day we would ourselves become victims of the Mississippi Mudslide. We hoped not but then again it is an act of affection so we were somewhat confused.

To freeze a piece of shit and roger your partner with it. As it melts the poo will slide down her/his legs.
When she awoke I told her that she had left a candy bar in her ass crack by mistake; I was ashamed to admit I had given her the Mississippi Mud Slide while she was sleeping.

It is when you have diarrhea and you eject your watery feces all over your partner during intercourse. The diarrhea has a muddy appearance and is slippery (like a slip ‘n’ slide) which is why the term “mudslide” is used.

A Mississippi Mudslide is the next step after a Cleveland Steamer. You take a dump on a girls chest (the Cleveland Steamer part) then use that as lube to titty fuck her. It often precedes a Chocolate Covered Vanilla Popsicle (moving up and into the girls mouth to erupt).
I met some nasty ho at the bar last night and gave her a Mississippi Mudslide. It smelled horrible but the crazy bitch was into it and she actually requested a Chocolate Covered Vanilla Popsicle!

The act in which a male puts his penis into a females anal cavity, and then proceeds to urinate inside of her. Result is a digusting mess that smells like sewage.

The process by which the woman lays down on her back and the guy spreads his butt cheeks apart and begins to rub his asshole on her face until there is a black streak from her chin to her forehead.
Oh man, I can't wait to give this chick a Mississippi Mudslide.
