nagger ninja

A human being having the power to know everything about anything. They also have supper strength. They are not able to fly because no Ninjas are able to fly, thats just crazy. They are normally found with curly hair and are full blood jewish. The way you know if you've really found a real life Nagger Ninja is by them presenting legal documentation of a black belt with their name on it. Nagger Ninjas can be very dangerous, DO NOT approch them if you are half cuban and half bosnian.

OMG, i just saw a Nagger Ninja fly!

that would be a perfect example of something crazy.
