i do have a select few white friends that i let them say nigga. some of my white friends grew up around black ppl so its pretty much all they know. Then some of my other white friends call each other nigga and i dont mind when they say it. I'm cool with them and still view it as a term of endearment.

I know puerto ricans that call each other nigga. Nigga is becoming a universal word. its not just black anymore.
