Fire Mudd 

A fast traveling, preferrably liquidy dump that comes out quick and burns like hell either before, during, or after the deed.

"Dude I woke up with some crazy fire mudd this morning!"

Muddy Fire Pit

When a female defecates and wipes from back to front, resulting in a small quantity of feces in her vagina.

John: Dude, her pussy is nasty - she's got a muddy fire pit.

Scott: A what?
John: Muddy fire pit. She got some shit in her snatch.
