a member of the counter-culture "revolution" from the mid-1960's until the early 70's. Generally, the polarized youth and young adults from that generation who were tired of the ongoing war in Vietnam, the social policies of Richard Nixon (then president) and the escalation of nuclear conflict with the USSR. Generally speaking, a movement of youth manifested in folk-style music, organic patchwork clothing and long hair as a rejection of the normative values of the time frame in lieu of peace, love and acceptance of others. Also, generally associated with casual sex coinciding with the advent of "the pill" (an oral contraceptive) and drug use dabbling mostly in psychedelics ranging from marijuana and hallucinogenic mushrooms to LSD-25. Most accept that the era culminated with the rock festival Woodstock in New York state, waning thereafter to the forthcoming "Yippie" or hardline political activists like Abbie Hoffmann of the mid 1970's.
