> The term is a compound word joining goy, a Hebrew and Yiddish word for a non-Jew or gentile,[4][3] and slop, meaning food waste or refuse of low quality

So you're telling me that a word which has "slop" in its origins is itself the origin of "slop"?

This must be the first case of circular etymology!

That’s a different word. And it’s a word that came long after “slop.” It only makes sense if you know what “slop” means. I don’t actually understand why you’re linking me to this.
