Today it is used mostly by black individuals to make fun of white individuals. Though dosent have as much impact as its cousin word "Nigger" (cuz white people weren't mass enslaved in America)
White Guy: Hehehe....Hey man
White Guy: (whispers) stupid nigger
Black Guy: What was that bitch?!
White Guy: *runs away*
No one is fuckin better than anyone they are equal, until your actions or reputation lowers your social status and respect, of course.
