Ninja Jump

Whilst you're in a deep sleep/sub concious state, its as if a ninja has sneaked up on you, shoved you and vanished into thin air causing your arms and/or legs to spasm and jump randomly - sometimes so violent that it causes you to wake up.

Just got back from my night-shift at work, got into bed where my girlfriend was sound asleep, she ninja jumped and kicked me in the fucking gooch!

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!
