Nigga

1) "Nigga" and "Nigger" are two completely different words, said with totally different contexts. NEVER say Nigger, CAREFULLY say Nigga.
2) In the modern day, almost everyone (of different races) casually says "nigga" amongst their closest friends. If you are MY nigga - that means you are one of the most loyal, trusted, dependable, needed friend I have. If you are just A nigga (not my friend) then most likely you are either being funny, foolish, ghetto, cheap, or overly confident in a social context.

3) People should stop saying "nigga" after they stop seeing one... which will probably never happen.

"This nigga right here being hella stupid!"

"Can I get a slice of that pizza? I can?? Thank you MY NIGGA"
