The following comes from the wikipedia.org entry titled “Scofflaw”:

Scofflaw is a noun coined during the Prohibition era meaning a person who drinks illegally. It is a compound of the words scoff and law, meaning one who mocks or ridicules the law. The meaning has since been extended to describe one who flouts any law, especially those which are difficult to enforce, and particularly traffic laws.

“Scofflaw” was the winning entry of a nationwide competition sponsored by the Boston Herald in the year 1924. The word was submitted by two separate entrants, Henry Irving Dale and Kate L. Butler, who split the $200 prize equally. The term scofflaw was deemed the best and most suitable out of over 25,000 entries.[1] 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. It is still used frequently in reference to cannabis prohibition. The word itself remains a symbol of the Prohibition era.

Now thanks to me, my lovely wife, Ken Burns’ documentary on Prohibition, and wikipedia, you too know what the word “scofflaw” means and why it was ironic to see an alcoholic beverage named after it.
