Ninjiin - a euphemism for psychotic, paranoid, angry women who take out their rage by burning random things, but mainly people.

She looks like a bit of a ninjiin to me.

Ninjing 

Displaying the abilities or likeness of the ninja.

Last night, no one knew we were present, which was in large part due to the fact that we were ninjing in the shadows.

Ninjin 

A Ninjin is a carrot-like being. Ninjins are known to run like vegetables, especially carrots. Ninjins have a kiwifruit fetish. Their sexuality is about as straight as a roundabout. Ninjins are extremely annoying and awfully strange

When I was walking around today I saw a being running around like a carrot. I told my friend and they said it was a " Ninjin".
