What if a black person uses the word "nigger" to refer to another black person? This is generally considered acceptable. Is it a lie? It still means, "I am superior to you because you are black"; however, as this is, in context, impossible, it becomes a piece of ironic theater, the gist of which is, "We are both black, and that is important, because the world looks down on us for it".

But is it a lie? It is an exagerration, not entirely false.
