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.
