b'nate

I have heard the term "b'nate", pronounced, "bihNATE", used to mean leave, or "jet", "bolt", "bounce" or "peace out", in the context of, "This place is wack. Let's b'nate."

Has anyone else heard this term or can anyone tell me if this was originally a black American slang term as I understand it to be?

Paul,
I have never heard b'nate. Jet or bounce was always popular in my town. You should start using it and see if it catches on....;)
