Toprock

Toprock is a major element of b-boying and b-girling. It generally refers to foot movement performed from a standing position, relying upon a mixture of coordination, flexibility, rhythm, and most importantly, style. It is usually the first and foremost opening display of style, and it serves as a warm-up for transitions into the more acrobatic maneuvers of downrock.
Breakers may devote considerable time to developing their toprock, and the style they display is a point of pride.
Toprocking is a style of dance in and of itself, and the Indian step is the most commonly performed toprock "move". However, toprocking is very open to modification for individual style. For this reason, it has come to incorporate elements of salsa, Lindy Hop, Liquid dancing and the Robot. In particular, uprock, often confused with "toprock," is a competitively-oriented type of dance consisting of foot shuffles, spins, turns, and creative movements that may mimic combat.
