Nigrocity

A level of such rage and aggression that cannot be described by ferocity, its sister word. To rage beyond control. To be so upset, you are foaming at the mouth and everything is a target. This is ferocity on crack.

"Shit did you see Brenden after we got kicked out? Yeah man, his nigrocity was through the roof. Thought he was gonna kill a bitch."

"Doctor: I got the test results back....It seems the reason you can't hold a job is because you have disturbingly high levels of nigrocity in your blood. Patient: Oh dear God...."

Ninjality 

Proof of one being a ninja, or proof of ninjaness.
This can be done by a photo of you as a ninja(face cant be fully shown, and camra man must die), giving a piece of knolage known only by ninjas, or disapearing like a ninja.
Failure to prove ones Ninjality will resualt in death or the title of a wannabee ninja... which is equal to death... only a ninja may ask for proof of Ninjality....

Ninja: do you have proof of Ninjality?
ninja wannabee: what ality?
Ninja: ~has now decapated wannabee~
