Flip-Flops are those sandals invented by the Egyptians in about 1,500 BCE and perfected by the Brazilians in 1962. In the USA, flip-flops are named for the both the repetitive movement and the sound of someone walking in rubber sandals. However, nowadays, the word is most often heard in news reports or accusations, meaning a reversal of a stand or position, and the word is mostly used accusatorily. American politicians, for example, traditionally flip-flop on the issues of same-sex marriages, abortion and gun control.
The New York Times recently published an article entitled “Trump’s Flip-Flop on Taxes”. The Washington Post published an article with the heading, “Here’s Hoping Trump Flip-flops Even More”. And just to make you think, the Los Angeles Times published a column with the heading, “Beware the Politician Who Won’t Flip-Flop”.
Flip-Flop is also an electronic device or circuit that is capable of assuming either of two stable states, and you computer geeks probably know that already, and the rest of us don’t need to know any more than that.
