scofflaw

\ \ [20] Aside from proprietary names and some scientific terms, it is rare for words that are pure human inventions (rather than naturally evolved forms) to make a permanent place for themselves in the English language, but scofflaw is a case in point. In the US in the early 1920s, in the middle of the Prohibition years, one Delcevare King of Quincy, Massachusetts offered a prize of $200 for a word to denote someone who defied the law and consumed alcohol. Over 25,000 suggestions were received from America and around the world. In January 1924 King announced his chosen winner: scofflaw, a simple combination of scoff [14] (probably of Scandinavian origin) and law. Two people had submitted it (Henry Irving Dale and Kate L. Butler), and they shared the prize.

\ \ Whether because or in spite of its homespun transparency, the word caught on, and survives in America to this day, albeit somewhat broadened out in meaning: specific reference to illicit drinkers is no longer in much demand, but it is now used for someone who flouts any law.
