When you take a dump and it breaks off leaving a point on the remaining fecal matter so no matter how many times you wipe you still get a brown stripe on the paper.
I got the Doo Doo Crayon again no matter how many times I wipe I still get the skidmark.

Doo-doo rolled up inside newspaper and frozen in the freezer. Once frozen, the paper is peeled back to reveal the tip. This creation resembles a brown crayon, hence the name Doo-Doo Crayon.
Last night, we made some doo-doo crayons and tagged downtown.
