 Flagger groups, known as tribes, formed in New York City, Boston, Columbus, Philadelphia, DC, Los Angeles, San Francisco and South Florida in the mid 1990s, and were often part of the backdrop of the circuit party events mostly attended by gay men.These were soon followed by the formation of troupes in Minneapolis, Seattle, and Houston in the United States, and in Belo Horizonte, Brazil.It is considered disrespectful to commercialize this disco art form.
