Flip-flop (politics)
A "flip-flop" (used mostly in the United States), U-turn (used in the United Kingdom, Ireland), or backflip (used in Australia and New Zealand) is a sudden real or apparent change of policy or opinion by a public official, sometimes while trying to claim that both positions are consistent with each other. Often it will occur during the period prior to or following an election in order to maximize the candidate's popularity.
History
In his "On Language" column in The New York Times, William Safire wrote in 1988 that "flip-flop" has a long history as a synonym for "somersault". (He cited George Lorimer in 1902: "...when a fellow's turning flip-flops up among the clouds, he's naturally going to have the farmers gaping at him.") In the late 19th century, a US politician was called "the Florida flopper" by an opponent, Safire noted. The "fl" sound appearing twice is an indication of ridicule, he wrote. Citing grammarian Randolph Quirk, Safire pointed out that the doubling of the sound is also a feature in other two-word phrases used to disparage the actions or words of others, including "mumbo jumbo", "wishy-washy", and higgledy-piggledy".
