Someone who surreptitiously defecates in public by shaking the dookie out of his pant leg and letting it plop on the floor.
I was shopping at Wal-mart and saw a dookie ninja at the check out lane.

When you are shopping at a grocery store and witness as an old man shakes a small turd from his pant leg.
Last night in the produce department of Wal Mart I saw a geezer shake a small turd from his pant leg. I guess he shit himself and it rolled right down his leg on onto the tile floor. Geezer was a Dookie Ninja!
