Use of the words: nigger, niggaz, niglet, or any other derivation as intended to seperate those with dark skin and of African descent from all others.
Use of this term by such dark skin individuals toward others of similar heritage is sometimes thought of as acceptable. Doing this however keeps the word in circulation and promotes the use of the N-bomb by people of any race.
Black guy uses the N - bomb in referring to his friends including both black and caucasion people: Hey niggaz--hurry up, we'll miss the show!
Just to recap what his friend said the white guy also drops the N - bomb:
Hurry up niggaz--we're going to be late!
Then the scuffle ensues.
Moral: if you are offended when anyone uses the N-bomb toward you; don't use it toward others.
