look up any word, like rimming:
Jewish racing gold is the description of certain shades of the colour gold. It is most often applied to cars painted in a gold colour, though can also be applied to describe other items of this colour.

It is derived from the stereotype of Jewish women of a certain age having a prediliction to gold-coloured clothing and accessories, and is therefore mildly perjorative.
Shabbat shalom, her car is jewish racing gold!
