I wouldn’t worry about the slur, especially if there is a descriptive or historical meaning to the slur that connects to what you are trying to convey.

I wouldn’t use an obscure term and then describe it. Either the context of the rest of the sentence or paragraph provides meaning to the term (use it) or you should just not use the term and describe what it is.
