Make a speedy departure, run away, as in I looked around and he was gone-he'd taken a powder. This slangy idiom may be derived from the British dialect sense of powder as "a sudden hurry," a usage dating from about 1600. It may also allude to the explosive quality of gunpowder.

To make a quick departure; run away.

To leave quickly. The origin of this expression is obscure, even though it is relatively recent (twentieth century). Since about 1600 a powder has meant “a hurry,” possibly derived from the speed of gunpowder. “Ile sett you in with a powder,” that is, with a rush, appears in a play, Club Law (ca. 1600), by an unknown writer. This meaning persisted well into the nineteenth century, mainly in Britain. In the 1920s, however, in popular literature, characters departing in haste were said to take a runout powder. P. G. Wodehouse used it in Money in the Bank (1942), “And have him take a runout powder? Be yourself, lady.” One writer has suggested this might refer to a laxative, but that interpretation seems unlikely. Moreover, the French have a similar expression, Prendre la poudre d’escampette, “To take the scampering powder,” or, in more idiomatic terms, “to bolt.”

Scram! This tough-guy phrase came from the days when a ladies' bathroom was euphemistically called the powder room, the place where women went, among other reasons, to apply makeup. As gangster movies would have us believe, a lady's escort who wanted to discuss a matter in privacy with another gent told her to “take a powder.” Similarly, a genteel way to say you were going to the ladies' room was “I'm going to powder my nose.”
