Double Whammy : Phrases
A double blow or setback.
A whammy was originally an evil influence or hex. It originated in the USA in the 1940s and is associated with a variety of sports. The first reference to it in print that I can find is in the Syracuse Herald Journal, October 1939:
'Double whammy' emerged not long afterwards, as seen here in the Oakland Tribune, August 1941, in an interview with the eccentric boxing manager Wirt Ross:
Ross was well-known for his tall tales and flowery language. It is quite possible that he coined the term in that interview.
'Double whammy' is often associated with Al Capp's Li'l Abner cartoon strip, which featured the phrase several times. In that it referred to as an intense stare which had a withering effect on its victims. For example, this piece from Li'l Abner July 1951:
The phrase came to be used widely, in the UK at least, during the Conservative Party's 1992 election campaign. The Tories used a poster to undermine the Labour Party. It contained the text "Labour's Double Whammy" and, on the boxing gloves, "1. More Taxes" and "2. Higher Prices". The poster proved to be a highly effective part of the campaign for the Conservatives - who won the subsequent election.
