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!

Alcoholic Ninja

The one person you always try to,avoid at the bar but he somehow seems to show up out of nowhere and spews his drunk stupidity at you.

My girlfriend and I were having a great time at the bar last night and out of nowhere Pat appears , completely drunk , talking about his latest female conquest. He is such a fucking Alcoholic Ninja!

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 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!

Infinity Ninja

1. A lemniscate (AKA the infinity sign, or a side-ways eight) that looks like a ninja. Once you see one you'll start seeing them everywhere.

2. The most powerful ninja in the world, one who can control time, destroy the universe, etc.
What's more, HE'S EVERYWHERE. Look at your keyboard sideways, between the 7 and the 9. He's there, looking at you.

1. (tilt your head)

8 ----> (8)X-< It's a ninja!

2. Ninja 1: He's too much for us....
Ninja 2: Where did we get the idea that we even had a chance? There's a whole army of them now......
Infinity Ninja: ∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞
