What is the origin and meaning of the phrase "move off the dime"?

Move, or get off the dime means to stop procrastinating and get going. It dates back to the 1920's and the dance hall days when it cost a dime for a dance. Further definitions quoted here:

“Get off the dime” has been around since at least the 1920s, and today it’s generally used to mean, as defined by the Historical Dictionary of American Slang, “to take action after a period of indecision or procrastination; to act” (“Congress [should] get off the dime and adopt the … budget proposal before it,” President Ronald Reagan, 1982).

“Get off the dime” dates back to the days of dance halls and “taxi dancers,” women employed by the halls to dance with strangers, usually for ten cents per dance (a grim occupation immortalized in the 1930 Rodgers and Hart song “Ten Cents a Dance”). A contemporary account, published in 1925, explains the phrase: “Sometimes a … [dancing] couple would … scarcely move from one spot. Then the floor manager would cry ‘Git off dat dime!’” Similarly, “dancing on the dime” meant to dance very closely with very little movement, behavior that might well attract the attention of the Vice Squad and get the hall closed. Thus “get off the dime” referred both to the the customer as the “dime” he had paid and to the small spot (“dime”) on the floor where the couple seemed frozen.

The meaning of to get off the dime, as native speakers know, is ''to start moving; to stop stalling.'' But what's the origin? And why hasn't the old slang phrase faded along with the value of the 10-cent piece, in an era when hardly anything can be bought for a dime a dozen?

A dime, from the Latin decem, ''ten,'' is the smallest and thinnest U.S. coin. In metaphor, it signifies anything especially tiny. When you are driving, and mean to stop at a precise point, not in a general area -- you stop on a dime.

Thanks to Jonathan Lighter's "Historical Dictionary of American Slang," we have the activity that coined the phrase. Carl Van Vechter, one of the earliest modern dance critics and author of the 1926 novel "N***** Heaven" - a title nobody would use today - described the scene in a taxi-dance hall: "Sometimes a ? couple would scarcely move from one spot. Then the floor manager would cry, Git off dat dime!"

To dance on a dime was to grind bodies tightly together in clothed but sexual contact, without moving from that spot; taxi dancers working for a dime (immortalized in the 1930 Lorenz Hart lyric "Ten Cents a Dance") were exhorted by their bosses to keep the customers moving. Thus, to get off the dime came to mean "to get moving."
