ninja vanish 

Secretly deleting your phone number from a girl's cell phone after you've had sex with her so she can never call you again.

Are you going to call Steve again?

I can't! My stupid phone deleted his contact information. Ah wells, I guess it wasn't meant to be.

Ninja Vanish!

my ninja 

A more tasteful substitute for "the N-word", used to show comraderie rather than feelings of racial inferiority.

Fight the power, you bitch-ass ninjaz!

Ninja Out 

To sneak out of place without anyone knowing.

To leave a place early without saying bye to anyone to avoid them making you stay

I don't want to drink anymore so I'm going to ninja out before anyone notices.

Danny always tries to ninja out early because he cannot hang.
