ninjabitch 

A girl who seems sweet and loveable and awesome when you start dating her, but turns out to be a bitch later, particularly by cheating on you.

"So, how are things going with you and Lisa?"

"Oh, we broke up man. She turned out to be a complete ninjabitch-- She fucked my best friend and didn't tell me for three months."

ninjaiceaphobia 

The perpetual and irrational fear of Ninjas, or Ninjas associated with Robert Van Winkle, A.K.A "Vanilla Ice" which said Ninjas are considered a Vanilla Ice posse.

I'm afraid of NINJAS!!! In which case said Ninjas:* Come forth to unspecified locations and remodel your home to suit their needs. Which includes but isnt limited to: a Ninja training facility and or recording studio where the song "Cadillac Ninjas" will be played incessantly until your ears bleed or you want to stab yourself in the face to make the pain stop.*Ninjas break dancing to "Ice Ice Baby" wearing parachute pants and gold chains while armed with samurai swords and ninja stars. This is the result of ninjaiceaphobia

Ninja Itch 

An itch that you can not find.

For example, Your arm feels itchy but when you scratch it you realise your arm isn't itchy - it feels it - and the itch is realy on some other part of the body. And we all know how stealthy ninjas are, so this is realy a "Ninja Itch".
