[1960s+ Counterculture; fr hip]
member, during the 1960s and 1970s, of a countercultural movement that rejected the mores of mainstream American life. The movement originated on college campuses in the United States, although it spread to other countries, including Canada and Britain. The name derived from "hip," a term applied to the Beats of the 1950s, such as Allen Ginsberg and Jack Kerouac, who were generally considered to be the precursors of hippies. Although the movement arose in part as opposition to U.S. involvement in the Vietnam War (1955-75), hippies were often not directly engaged in politics, as opposed to their activist counterparts known as "Yippies" (Youth International Party)
