What's on your mug?

Someone who has the ability to mindfuck others. Someone who is stealth enough to complete missions with other ninjas that involve high risk situations. A ninja can usually "ninja" information out of other individuals who are clear 'un-ninjas'. Ninjas are usually dressed casually, and people don't usually peg these people as actual ninjas, but rather, ordinary and normal girls. Watch out though, there couldbe a ninja at your workplace. And she could ninja the shit out of you.

co-worker: blah blah blah blah blah ninja: (in her mind) - good to know I just ninja'd the shit outta you bud. I'm going to go tell my other ninja this classified information.

Ninja is a coded word whites use say black person so we don't say nigger it's a little to racist to say nigger and it can get your ass whooped especially In jail or the hood ninja sounds almost like nigger and all whites seem like the automatically know that it means a black person and it's better to say and it will keep you from getting your ass whooped in the hood or jail

An intense sexual position involving a man and a woman and a dildo, the way it is performed is first, you turn off all the lighs in the room second, you start banging the girl in the ass third, you shove the dildo in her ass and pull out so she "does not know" fourth, you jump to her side scream NINJA and punch her in the face.

Jenny:Damn, i got ninjad pretty hard last night. Me: Yeah i fucking owned you

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.

*Roundhouse Kicks someone through a wall* "Woah that's so frickin' Ninja!" *A very nice hat* "That hat is so Ninja!" *Walks on the grass when there is blatantly a sign with clear instructions not to* "Shit, that dude is ninja." *Prefers Pirates* "What a queer"
