Scofflaw is a noun coined during the Prohibition era which originally denoted a person who drinks illegally, or otherwise ignored anti-drinking laws.
"Scofflaw" was the winning entry of a nationwide competition to create a new word for "the lawless drinker," with a prize of $200 in gold, sponsored by Delcevare King, a banker and enthusiastic supporter of Prohibition, in 1923.
[1] Two separate entrants, Henry Irving Dale and Kate L. Butler, submitted the word, and split the $200 prize equally.
[2] The word was from the outset frequently used until the eventual repeal of Prohibition in 1933.
It experienced a revival in the 1950s, as a term for anyone who displays disdain for laws difficult to enforce.
