The time when you look at a clock and realize that a large portion of time disappeared. It is NEVER 'ninja o'clock', because by the time you've realized the time, it's at least a half-hour after you expected.
Friend 1: "Dude, what the hell happened to the day? I had that interview for that job."
Friend 2: "Ninja-thirty happened, son... remember that 'I'm only going to play a couple games' Madden marathon we just had?"

to ninja: to chop a person in the back of the neck while open and there is no truce in affect. Or possible if you want to just be an ass whole or they are being a bitch you can breack truce. it is not a ninja if you hit there shoulder, head or face. there is a code for what u can do or how you can ninja someome. If u r truced w/someone u have to tell them when someone is gonna ninja them. if you have a truce with someone that is about to get ninja-ed and the person that is gonna ninja them you have to stay out of it and not say anything. you are basically nuetral.

When someone, usually your parents, randomly springs a topic, usually sex related, onto you unsuspectingly. Much like a ninja attack its always a surprise and sometimes its deadly.
