Beat Generation
Kerouac introduced the phrase "Beat Generation" in 1948 to characterize a perceived underground, anti-conformist youth movement in New York. The name arose in a conversation with writer John Clellon Holmes. Kerouac allows that it was Huncke, a street hustler, who originally used the phrase "beat", in an earlier discussion with him. The adjective "beat" could colloquially mean "tired" or "beaten down" within the African-American community of the period and had developed out of the image "beat to his socks", but Kerouac appropriated the image and altered the meaning to include the connotations "upbeat", "beatific", and the musical association of being "on the beat", and "the Beat to keep" from the "Beat Generation" poem.
Free love
From the late 1940s to the 1960s, the bohemian free-love tradition of Greenwich Village in America was carried on by the beat generation, although differing with their predecessors by being an apparently male-dominated movement. The Beats also produced the first appearance of male homosexual champions of free love in the U.S., with writers such as Allen Ginsberg and William S. Burroughs. Like some of those before, the beats challenged a range of social conventions, and they found inspiration in such aspects of black culture as jazz music. The Beat movement led on the West Coast to the activities of such groups as the Merry Pranksters (led, according to Grateful Dead historian Dennis McNally, not by novelist Ken Kesey, but by hipster and driver Neal Cassady) and the entire San Francisco pop music scene, in which the implications of sexual bohemianism were advanced in a variety of ways by the hippies. The study of sexology continued to gain prominence throughout the era, with the work of researchers Alfred Kinsey and Masters and Johnson supporting challenges to traditional values regarding sex and marriage.
