The liquefied diarrhea excrement that rolls out of your pant leg when you walk and defecate at the same time. Usually the expectation is that the excrement will be a solid and they can perform a stealth deudrop, but are often surprised when the feces is liquefied.
Fred was walking behind Martin when he noticed Martin's pant leg turn born and wet. Martin then ran to the nearest bathroom. Jon walked up as Martin ran away and asked what was wrong. Fred replied, "I think he tried to deudrop, but it was a muddy deudrop. Poor guy. hahahaha, ahhhh it stinks."

Freshly wiped poop on toilet paper that is being thrown over the stall wall which gently descends on the person in the adjacent stall.
My buddy Todd and I were in the bathroom dropping a deuce at the local Arby's when I told him to look up and tossed him a muddy parachute.

The act of cunnilingus while the receiver defecates on the toilet, thus leaving a streak of feces between the chin and lip of the performer, which resembles Howie Mandel's soul patch from the mid-00's. Analogous to the blumpkin.
Emily: I heard Brian gave Tiffany a mean muddy Mandel for their one year anniversary!
Stephanie: Tiffany's so lucky - she found a keeper for sure.

When you are performing analingus on your partner and they accidentally or purposely defecate in your mouth and you let out a squeal reminiscent of the sound a bagpipe makes.
