While I was reading a couple articles with a similar type of idea, I wondered if there were some substitutes for "nigga" that other ethnicities than black people use? That is the word is supposed to be a pejorative outside the ethnicity but not pejorative within.
For example, within the Black community, "What's up nigga?" is a friendly term, but someone using that word who is not black would likely cause problems.
I couldn't think of any other similar example where a pejorative term has been claimed and rehabilitated within the group against whom it would normally be a racist slur.
Are there terms used in a similar way by other ethnic groups?
