jaywalker

Origin

From jay (“a stupid person”) + walker; jay walker (“a pedestrian who doesn't pay attention to the road, endangering themselves and obstructing horses, carts, and automobiles”). First use appears c. 1917 in Harper's Magazine. Coined in analogy to the older turn-of-the-20th-century term jay driver (“a driver who doesn't pay attention to the road, endangering horses, carts, bicyclists, and pedestrians”). Promoted by driving enthusiasts and automotive concerns to clear the roads of obstructive pedestrians by making it illegal to walk in the middle of roads.
