Breakance, breaking, b-boying or b-girling is a street dance style that evolved as part of the hip hop movement among African American and Puerto Rican youths in the South Bronx of New York City during the early 1970s. It is normally danced to pop, funk or hip hop music, often remixed to prolong the breaks, and is a well-known hip hop dance style. A breakdancer, breaker, b-boy or b-girl refers to a person who practices breakdancing.
