What is a B-boy?
A B-boy or B-girl is a person devoted to the culture of hip-hop, who participates in the dance style of breakdancing or breaking. The term “b-boy” originally referred to the name of the people who danced during a DJ’s drum break.
Four basic elements form the foundation of B-boying:
 Toprock: the upright dancing and shuffles that B-boys do when they enter a circle.
Downrock the footwork, or dance steps performed on the floor.
Freeze:poses thrown into dance routines that add punctuation to certain beats and sometimes end a set.
Power moves:acrobatic moves of circular motions involving spinning on the floor or in the air.
