When you wipe after you shit and the paper comes out clean... Like the shit was never there... mysterious and stealthy...
I love it when I take a ninja shit... I only have to wipe once!

Any persons, male or female, who deposits fecal matter that has such strong nauseating odor that he/she has to lift the front of their shirt to cover their nose, therefore resembling a ninja.
"Man, after I ate all of that limberger and ice cream I had to run to the bathroom and take a smelly ninja shit.

When some takes a number 2 so quickly and quietly that the person must have the shitting skills of a Ninja.
Lawrence, you were in the bathroom for 30 seconds and you have created an odour that reminds me of a dumpster behind an Indian restaurant. That Ninja shit was so quick and quiet that I hardly noticed that you were gone.

Where you shit so fast, it'll seem like you never left where you were.
If you're on the job and you have to go, but you're afraid to leave.... take a ninja shit.

To sneak into the bathroom while someone is mid-shower, take a shit, and exit, leaving only the scent of shit wafting about the bathroom on the steamy air to announce the shitter's presence.
"God dammit! Brian ninja shit me again."

Its when you take a big solid shit kicking its way out of your ass, the head sticks out of the water and you think (i'm gonna need a plunger to beat this fucker down), thers no need to wipe, and when you fush it disappears in a cloud of brown mist!
The ninja shit almost made me shit my pants, i got it out and went to beat it down with a plunger and the fucker disappeard in a cloud of mist!

When you have finished going Number Two, and suddenly feel more on the way.
"Man, got half way out when I got struck by Ninja Shits"
