Muddy Mississippi 

Where you willingly sit down and let someone shit on your head and let the shit gradually role down.

Last night I got a muddy Mississippi and my hair has never been the same

Mississippi Mudd Butt 

Would normally be referred as diarrhea, but is horribly worse. M.M.B. could result in a rectal prolapse and death. This horrid case of explosive shit squirts creates a stench so horrible that can erode iron, cause brain aneurysms, will knock a man unconscious within a 69 mile radius. M.M.B. is normally caused by malnutrition and consuming more than 3 prunes in 2 minutes. There was once a man who had a case ofM.M.B., he did not live to tell his story. While using the bathroom, the blast of his M.M.B rocketed him off the toilet, thrashing his limp body to the solid pavement. The force of the impact broke all of his bones, paralyzed him then killed him instantly. Learn from his experience.

D00d, I think I might have Mississippi Mudd Butt . Its br00ta1, I need to use your shitter.
