closet ninjas 

The act of gathering up some friends of yours to hide in a closet in ninja costumes and then while in the same room fuck your girlfriend/boyfriend that you found cheating on you. Make sure its a painfull experience for the other person of course and while in the sex make a key word for the friends to come out of the closet and beat the shit out of the girl or boy. Then have them run off.

Shirly why are you all beaten up?!
I was had by the closet ninjas.

Ass Ninjas

An elite group of ninjas that discretely enters homes and rapes the shit out of whatever is living in them.

Also, Ass Ninjas are a threat used by parents, telling their children that if they don't go to sleep Ass Ninjas will get them.

Last night Ass Ninjas broke into my house and raped me!
Go to bed now or the Ass Ninjas will get you!

Ponts Ninjas

The awesomest group of ninjas in the universe. You would be lucky to be invited to join this wonderful group. This group consists of three lead members, the rest are followers. These people find pants they like and "steal" them. Even if they happen to be on a person.

ZOmg, that girls one of the Ponts Ninjas. (you can tell by her mask and the awesomest wacky pants with gomushins)

nuclear ninjas 

A secret level of ninja that is rarely talked about, because no one knows who they are. Along with having superior ninja skills, they are skilled in the ways of "secrecy", and do not let others hear of their glorious ninjatastic ways. The creator of this special league of ninjas is said to be so great, his supreme awesomeness cannot be expressed in words. Not even the nuclear ninjas have seen him.

Guy: Dude! My algebra teacher is a total douche. I tried to get him fired, but it didn't work!

Some Other Guy: If all else fails, use the nuclear ninjas. They always get the job done.
