muddy deudrop
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."
