Beat - as in Beatnik
In the entertainment world, “Beat” was transmuted into “beatnik,” a word invented, in 1958, by the San Francisco Chronicle columnist Herb Caen. The term derives from Sputnik, which was launched into space a month after the publication of “On the Road.” (Why is a beatnik like Sputnik? They are both far-out.)
