[Tournaments-HotA] Blitz Jebus Cross - 2

I understand that the point is "is goy," meaning it's "goy" in English.

What does "goy in English" mean? Could you put in a little more effort to make it immediately clear what you mean? I looked up "goy in English" in a translator, and it just says "goy." That doesn't make things any clearer. The main question is, what does the word "goy" mean, and why is that important?
