Duncan

The pile of shit left beside the toilet at Myers by some punk ass kids.
The act of crapping on the floor, to annoy other patrons and janitorial staff of public washrooms.

I was out grocery shopping with the old lady and wet to the can. Some jerk laid a Duncan.

Just for kicks, my buddy left a Duncan at a Walmart.
