The term "Beatnik" was coined by Herb Caen of the San Francisco Chronicle on 2 April 1958, a portmanteau on the name of the recent Russian satellite Sputnik and Beat Generation. This suggested that beatniks were "far out of the mainstream of society" and "possibly pro-Communist". Caen's term stuck and became the popular label associated with a new stereotype: the man with a goatee and beret reciting nonsensical poetry and playing bongos, while free-spirited women wearing black leotards dance.
During the 1950s, aspects of the Beat movement metamorphosed into The Sixties Counterculture, accompanied by a shift in terminology from "beatnik" to "hippie". Many of the original Beats remained active participants, notably Allen Ginsberg, who became a fixture of the anti-war movement. Notably, however, Jack Kerouac broke with Ginsberg and criticized the 60s protest movements as an excuse to be "spiteful"
