Concept and etymology

    The hippie (or hippy) subculture was originally a youth movement that arose in the United States during the mid-1960s and spread to other countries around the world. The word 'hippie' came from hipster, and was initially used to describe beatniks who had moved into New York City's Greenwich Village and San Francisco's Haight-Ashbury district. The origins of the terms hip and hep are uncertain, though by the 1940s both had become part of African American jive slang and meant "sophisticated; currently fashionable; fully up-to-date". The Beats adopted the term hip, and early hippies inherited the language and countercultural values of the Beat Generation. Hippies created their own communities, listened to psychedelic rock, embraced the sexual revolution, and some used drugs such as cannabis, LSD, and magic mushrooms to explore altered states of consciousness.  Источник
