mississippi mud butt
When you didn't quite wipe your ass enough after shitting and then start doing something very active that causes sweat to build up and mix between your ass cheeks.
Hugh:Man my ass hole boss rushed me outside the bathroom while I was dropping off the mexicans at the pool and I didn't quite wipe right and now I'm super uncomfortable with this killer case of Mississippi mud butt.
G.Rection: Man Hugh you should have just told him to go eat a big fat dick and finished that bowl blaster right.
