"The origins of the word beat are obscure, but the meaning is only too clear to most Americans. More than the feeling of weariness, it implies the feeling of having been used, of being raw. It involves a sort of nakedness of the mind." ["New York Times Magazine," Oct. 2, 1952]
" 'Beat' is old carny slang. According to Beat Movement legend (and it is a movement with a deep inventory of legend), Ginsberg and Kerouac picked it up from a character named Herbert Huncke, a gay street hustler and drug addict from Chicago who began hanging around Times Square in 1939 (and who introduced William Burroughs to heroin, an important cultural moment). The term has nothing to do with music; it names the condition of being beaten down, poor, exhausted, at the bottom of the world." [Louis Menand, "New Yorker," Oct. 1, 2007]
Members of the “beat” movement in the United States in the 1950s. Beatniks frequently rejected middle-class American values, customs, and tastes in favor of radical politics and exotic jazz, art, and literature. The movement was often classified as bohemian. The poet Allen Ginsberg and the novelist Jack Kerouac are examples of beatnik authors.
Note: “Daddy-O” (a term of address); “Cool, man, cool”; and “strictly dullsville” are examples of slang expressions used by beatniks or by people trying to sound like beatniks.
