Breakdancing is mostly improvisational moves or steps. The emphasis is on energy, movement, creativity, and an element of danger. It is meant to convey the rough world of the street gangs from which it sprang. Generally, it is also connected with a particular style of dress worn sideways or backward, and sneakers (required because of the dangerous nature of many of the moves). Breakdancing, also called breaking or b-boying/b-girling is an athletic style of street dance.
