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 Elaine's "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.

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.
