MudBut 

Mud But is the way you feel after you've had McDonalds for breakfast.

I just had a B.L.E.T. Bagel from McDonalds and Now I've got MudBut. I'm pissing through my asshole.

mudbut 

A Mudbut is a small mythical woodland creature found in rural central Pennsylvania. This creature is slightly smaller than a cat and extremely fuzzy. To see this animal would remind you of a koala bear mixed with a household cat. It gains its name by the sound it makes which is in a very highpitched light voice it say "mudbut"

Holy crap there's a mudbut!

Mudbutt

When you take a shit and there’s literally more poop on the toilet paper than there is in the toilet, and the poop is extremely sticky and thick (almost tar like)and impossible to clean off your asshole without scrubbing intensely in the shower. Usually happens when you eat too much junk food.

P1: “WTF took you so long in the bathroom? Were you writing a novel or something?”
P2: “Sorry, had a bad case of mudbutt. It was like the labrea tar pits down there.”
P1:”Maybe if you didn’t eat all those god damn Doritos every day and ate a fucking salad once in a while, you wouldn’t have that problem.”

Mudbutt

When thine cheeks of the buttocks become slathered in the fudge from ones own factory.

"Oh my goodness, that Thai food gave me a severe bout of the mudbutt!"

Monday Muddbutt 

Happens during football season. After a long Sunday afternoon of drinking cheap beer stuffing your face with mostly fried food like chicken wings nachos hot dogs etc... You wake up with a painful urge to blow the bottom off the toilet. The poo will have thick pasty texture with the occasional undigested corn chip. Then we have the dreadful aftermath of wiping. this usually take large quantities of toilet paper that will most likely clog your toilet. The first couple rounds of wiping is just for the bulk of the muddbutt. You could be there for hours wiping away but is best if you just hop in the shower rinse off and push the rest down the drain with your big toe.

"Only thing I hate about football Sunday is the Monday muddbutt!"

My butthole. The smell of a fart or other bad smell.

Joe: "What's that smell?"

Dave: "That's mubutol"
