Shiksa

[Becky]

A Gentile girl or woman, especially one who has attracted a Jewish man. The term derives from the Hebrew word sheketz, meaning the flesh of an animal deemed taboo by the Torah. Since a Jewish man marrying a non-Jewish woman is taboo also, this word applies to her.
Traditionally this is a derogatory term, though in modern times it has also been used more light-heartedly. For example, [Seinfeld] once did an episode about Elaines shiksa appeal.
The ideal shiksa is a blonde [WASP] who look like the opposite of a stereotypical Jew, but in reality, many shiksas are brunettes who might pass for Jewish themselves.

[Sarah]

An insulting term used by Jews to signify any non Jewish woman. Almost always used among Jews as a disrespectful offensive term for any non jewish girl or woman.
Its fighting talk.

[Justin Bieber]

Term used by [jappy] and spoiled jewish ladies to refer to their gentile cleaning lady or nanny.
