A non racial expression with roots from Nyack Middle School. It does not mean any thing specific, but puts emphasis on your statement. Its also very nice for ticking people off on Xbox live, like nigynigz
Its often used with the word like before it:
Jaqwondraykisha: Hey did you see that Kool-
Aid commercial last nigh-
Me: Yo I dont care like Nigy Nigz!
