So you get thrown out of the house if your boyfriend is Arab? Is that it? :)

I think we are supposed to assume that the name denotes a hated minority that we would all have fun belittling. What minority was left open either on purpose or by accident as maybe the original poster didn't know that the name is rather common to lots of areas.

A little too dated for my tastes.
