When you have to pee and poop at the same time.
-"Man, I just peeooped, and I sure do feel better now."
-"I hope traffic starts moving soon. I really have to peeoop!"
A mixture of Urine and Fecal waste from a bird out of thier peeoop hole. Commonly seen on car windows and city ledges around the world. (A.k.a. Bird Waste)
