Scofflaw:
Scofflaw is a noun coined during the Prohibition era to mean a person who drinks illegally. It is a compound of the words scoff and law. Its original meaning was someone who mocks or ridicules anti-drinking laws, but has extended to mean one who flouts any law, especially those difficult to enforce, and particularly traffic laws.

Used by my Arts Editor last night. Couldn’t remember last time I’d heard it, that must mean something significant.
