N Word Jim - A joke that only works if you're white and your black friend

A joke that only works if you're white and your black friend is either cool with it or too tired to fight back.

My friend used it in a joke and the black guy laughed it off.

I used it in a DM and he replied with a meme about it.

My friend used it in a rap song and the black guy was like, 'Okay, I'll let you slide.'
