Adjective.

Basically another word for cool. Except cooler, as its the word Ninja. Similar to badass in defintion yet far more badass, i think the best explanation of this word is infact 'Ninja'.

This is going to happen. It's Inevitable. It's going to happen big.

It will grow and spread across the Internet like wild fire with a shuriken.

Ninja is a game in which two or more people must play. The game is played by slapping each other on the hand. You can only make one move per turn. Once an attempt at slapping the other person's hand is made, you must keep your body in that position until your next turn.

Person 2: Hella yeah it does, I pwned you in Ninja!

Due to the fact we could not find any ninjas, we can not define them. We hope our apology is accepted. (But not by ninjas, for they never forgive, and they NEVER forget.)
That ninja is a great ninja, for we do not know what, who, or where it is.
