mud butt

the true "definition" of mudbutt,(all the rest are other peoples versions) is: the condition of the anal region where ones crevice between the ass cheeks becomes hot and saucy due to sweat, buildup of underwear residue, and poor wiping abilities. It is almost certain to happen to anyone on a real hot summer day if they:
1)wear dirty and/or heavy clothes
2)do not shower
3)have recently deficated
4)have participated in exercise

mud butt

(muhdh - buht) n. med. (usu. pre. by 'the') Mud Butt is a common affliction of the anus and the glutteal crevice, affecting mainly (but not limited to) "heavies". The condition usually occurs 30 to 45 minutes after defecation, especially if sufferer engages in physical activity within this time. Sweat and some remaining feces (though one's wiping habits may be immactulate) mix in the glutteal crevice, causing mild discomfort and, if not treated, a raw ass.

See how Rico is walking funny? He took a dum about 30 minutes ago. I bet he's got the mud butt.

Mud Butt: when shit basically drops out of your ass as soon as you hit the toilet. a muddy consistency, extremely wet shit and/or thick diahrea

a good example would be to eat 5 beef and bean burritos W/LOTS OF HOT SAUCE from taco bell or any generic texmex restuarant. Another example is the bag of fecies in the "mud butt" episode of The Chapelle Show
