You could use the word "nigga" but do not ever use the word "nigger." But a white guy does not use this word while talking to a black cause the blacks aren't gonna spare him. Use this word only if you are really in good terms with the other guy. A black guy at work wants me to say "what up nigga!" Dawg=dude...I freaked out the first time someone called me this. "Wuddup dawg?" Punked=tricking or teasing someone. "I punked ya all." Tight=cool...."That shit's tight dawg."
