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.
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!
