From Rap Dictionary
- The spelling, pronounciation, meaning and usage of the word has been changed to convey a sense of pride and defiance, thereby removing the racial distinctness of the original term. Although similar in spelling and pronounciation to the original, its meaning is completely different. The word "nigga", when used between close friends, is as positive as the word "nigger" is negative. In general, whites should avoid use of the term, even in a positive sense, unless they are absolutely certain it will not be taken as derogatory.
