The original dance of the Hip hop culture and one the original 4 elements of Hip Hop, the b-boy/b-girl is/was the title of the dancer who does the dance called b-boyin. Breakdancing is not accepted by most b-boys/b-girls in the Hip-Hop community since breakdancing was a term coined by the media. The "b" in b-boy/b-girl is disputed where most believe the "b" stands for "break" boy since the dance involves the break of the record. Other believe the "b" stands for "Bronx" boy since the dance as well as the culture of Hip Hop was born in the bronx.
Yo that b-boy has some of the dopest styles I've ever seen!
