Ninja Tank 

In RPGs and some MMORPgs, is another word for a character that can be in the forefront of the battle and survive the outcome due to sheer evasiveness rather than high armor and health. An example would be the assassin from the pseudo-MMORPG game "Guild Wars", especially in PvP mode.

"OMG, why duz teh PVP 'Sin not die? teh whole team is attacking him... I h8 ninja tanks

ninja studying 

when you pretend to be hard at work to get your mom off your back about homework, but you're really watching tv shows on hulu.

I was ninja studying last night. Learned everything off of bones and house. Think I'm ready for that biology test now!

ninja ant 

When one is running in the grass, on the blacktop, ect. and trips for no apparent reason which causes them to fall on their face.

I was playing football in my backyard and running in hot for a touchdown when suddenly at the 5 yard line damn ninja ants attacked me just before the victory.

Ninja Chord 

Usually played on guitar, but just the same on piano, this is a series of notes that requires the player to stretch their hands out as far as humanly possible.

I can't believe all that Ninja Chords that Al DiMeola played tonight!

Ninja Petter

A person who lacks the common sense to avoid antagonizing ninjas. A social klutz who does not know how to behave in public. Missing hands or fingers is a sure sign, but not required.

I can't believe that you just ate my BK mini burger off my plate, you are such a ninja petter!

You: Let's wait for the light to turn before we cross.
Me: You are such a ninja petter, there's no traffic.
