Jew Card

A figurative card used by Jews to guilt people/get out of a situation.

David: Ms. Stewart, I can't take the test tomorrow because --

Ms. Stewart: (Sighs) Lemme guess. You have ANOTHER Jewish holiday this week?

David: Actually, no. I'm just going on a vacation to Florida. I'm not using my Jew Card this time...

Jew Card

To lead someone on and then crush their romantic dreams because they aren't Jewish.

Boy: I like you
Girl: Ok. I like you too.
Boy: You aren't Jewish so it won't work
Girl: You just Jew Carded me.
