Combining the skills of a Ninja and the pleasure of sturbing, a ninja sturb is a stealth sturb. Often used when your roommates are in the room or just for the challenge.
My roommate came home early so I had to ninja sturb while he wasn't looking.

I ninja sturbed while watching a movie with my girlfriend, that way I could call her ugly her when she couldn't get me up later.
