its a slur used to call a black person slow or two black persons use it because their black. but when a white person uses it they would get beaten to a pulp ¯\_(ツ)_/¯
black person: Yo ma nigga.
black person: Eyyy playa.
white person: hey nigga.
black person: EYY WHAT THE FUCK YOU JUST CALL ME?BITCH ASS NIGGA.
white person: OH SHIT LOOK MAN I'M SORRY PLEASE DON'T KILL ME.
two definitions depending on a factor
If A black guy says it: Friend, pal, buddy.
If A white guy says it: Hey everyone! come over here and shoot me!
slur for "monkey man" or "black" this native slang is short term for the very known slur "nigger" which takes offense most of the time for the African American
