Stealth [Ninja] 

One who is very difficult to find, extremely mysterious and lightning fast. Stealth ninjas are nimble on their feet and NEVER fall.
"You can't see me, but i'm there."

-OH MY GOD, you totally almost fell down that snow hill.
-But I didn't.
-Yeah, lucky you.
-Luck?? I'M THE FUCKIN STEALTH NINJA. WE NEVER FALL(:

Stealthy Nipple-Ninja 

When you're about to cum, twist the girl's nipples as hard as you can so she freaks out and screams and is distracted, oblivious to the fact that you're blowing inside her

The day before my two weeks notice was up was the same day my asshole boss gets back from Sweden; therefore, I pulled the stealthy nipple-ninja on his wife. That'll learn em'
