simian silicus 

a more politically correct to refer to a "sand monkey" or an individual of middle eastern descent or terrorist.
It comes from the root words: Simian, Relating to, characteristic of, or resembling an ape or a monkey; and Silicus, a made up word that you can say is the latin definition of sand.

instead of calling someone a camel jockey call them simian silicus instead. It sounds more polite and they probably won't know that you're making fun of them.
