Half Kosher

When a Jew will eat non Kosher meat like beef and chicken, but won't eat a non kosher animal like pork or prawns. Something secular Jews do as they think it's better than fully breaking kosher, when in reality there's no difference.

Don:Hey Emily would you like some of my ham and cheese sandwich?

Emily: No Don! I can't have that! It's not kosher!
Don: Erm, Emily you do know that sandwich you're eating is non kosher chicken right?
Emily: Yeah but I eat non kosher meat, just not non kosher animals.
Don: So you're half kosher.
