Shake a leg is an idiom which means to hurry up, to get going. Shake a leg is usually used as an imperative, which is a form of grammar that is a command or request. The first use of shake a leg to mean hurry up is found in the New York Magazine in 1904.  The origins of the phrase shake a leg are murky, though there are claims that the term comes from the American Civil War, when after a battle, stretcher-bearers would violently jostle a leg or arm to see if they could elicit a response from a victim on the field and thereby ascertain if he were alive or dead.

The second of meaning of shake a leg is to dance, presumably having evolved from the terms shake a heel or shake a foot, which were popular terms meaning to dance in the 1660s.
