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!
