Ironically, “gypsy” was a slur for Egyptian. Because the people who originated the slur widely believed a false narrative that the Romani people were originally from Egypt.

I’m sure you were aware, but for completeness for anyone who happens upon this. Personally, I find it really interesting that this racial slur doesn’t even refer to their race! I guess it’s kinda like calling native americans “indian”, though many north american tribes have adopted the term at this point.
