To Nigger Oneself is to act in a way that brings both a "bad name" to black people and ultimately reinforces black stereotypes

Get the Nigger yourself mug.
Mostly said towards black people. If you are not black and the context isn't a hateful one, this can also be used ironically in a friendly conversation.
man 1: Have you met my sister?
man 2: More than met her, dude.
man 1: Go fuck yourself, nigger.

example 2:
man 1: go play another game you're so bad at this lol
man 2: Go fuck yourself nigger
