You do know that goy or goyim is mostly used as condescending way to refer non-Jewish ppl? It's the same way how Christians use heathens and the Muslims use kafir. Used to insult a non-believer.
You know, I think I did know that at some point, and just forgot about it. Although whatever, honestly. Jewish people put up with enough shit. If they want to get a bit snarky about it then they’ve kind of earned the right.
