Nigga- A word stemming from the root word, 'Nigger'. Today the word Nigga is used by uneducated ignorant blacks towards each other, equivalent to saying friend, buddy, homie, friend. If you aren't black, DO NOT USE THIS WORD, you will get your ass beat for being 'racist'. Hypocritical maybe?
Kashaun- You got my crack nigga?
Martez- Yea nigga, let's smoke it then go look fo sum nigga bitches.
Kashaun- YEA NIGGA!!!
