Goyish

Halloween is goyish Purim.

While any goyish woman can be a shiksa, the word is pretty much only applied to young, beautiful, available women.

A Yiddish term for bad luck is "yidish mazel", or "Jewish luck." The corresponding term for good luck is "goyish mazel."

"Fruit salad is Jewish. Lime Jell-O is goyish. ... Italians are Jewish. Greeks are Goyish..."
