The hippie subculture began in the 1960s as a youth movement in the United States that spread worldwide. Hippies embraced the counterculture values of the beat generation, formed their own communities, listened to psychedelic rock, supported sexual freedom, and used drugs like cannabis and LSD. They enjoyed traveling and creating their own music at friends' homes or outdoor parties. Emo subcultures emerged in Washington D.C. in the 1980s and derived from punk culture. Emos express sadness through black clothing, piercings, tattoos, and liking bands such as My Chemical Romance. They have a melancholy worldview that contrasts with hippies' optimism.
