Ninjaflip 

A 'ninjaflip' is a verb dictating the action of an arguably epic form of self defence.

Subject A is confronted by Subject B who intends to shake hands. Subject A grabs the wrist of Subject B and flips him/her over his head in an 180 degree motion, flipping and dropping them midair. This results in pain, and frequently laughter from an audience.

"Dude! Did you see Amy? The headmaster just tried to shake her hand and she totally ninjaflipped him!"
"Amy's pro."
"Agreed."

Ninjak 

1. Already being a pro ninja, Ninjak is one of the only few ninjas whom play video games. Whether it be on Xbox live or the PC, Ninjak is there. Sometimes you see him and sometimes you dont. If you met him before then you'll realize why Chuck Norris is no longer a factor in danger. Ninjak has the tendecy to expose himself too much, but few thinks its an open invite to a challenge. There are several impersonators of Ninjak whom have made a bad example of him thus far. He may not be the best of the elite gamers but be glad he doesnt know where you live. Despite the dangers of Ninjak he is an all around great guy.

2. The art of masturbaiting in public without being spotted

3. An Interwebs Ninja

1. Holy Crap! I just nailed a headshot on Ninjak!

*hiding under quilt* OH god why did i piss Ninjak off!

3. That "Ask a Ninja" guy is basically another Ninjak

ninjaukal 

(1)A form of the japanese samauri. A very old organization its origins are hundreds of years old. Much of its history has been lost and not many ninjaukals exist today yet they all have indomitable fighting skills in ninjitsu. No matter what weapons you use a ninjaukal will never die.

what the hell is a ninjaukal? he's a wicked juggalo clown representing the psycopathic family. Also known to knock a head off with a neck chop. Stealth enough to sneak in your house and have sex with your wife. Can manipulate the world into thinking that "eminem" is really the definition of a cocaine snorting homosexual. You remember that hotdog you ate last week? It was really a turd with sauerkraut on it.
