nigga
it's a word that can be used in bad ways and good but most use it in good or neutral they mean no harm by saying. Usally you wont get beat up for saying nigga unless you mean it offensively, or mean. Even though i'm white i only say it when i'm around my boys and which most of them are black or mixed. Other wise it's just slag for brotha or cuz...but best not for white people to say. Because it's a sign of respect.
Black:Wat it do my nigga?
White:Wat it do cuz?

SHOW THE RESPECT AFRICAN AMERICANS DESERVE!
