The headroll is a trick involving rolling an object or prop, typically a ball, around on the juggler's head. The most commonly performed version is rolling a ball from temple to temple, across the forehead. At some points during the trick, the object may be balanced in place at a certain location on the head. Points where the prop may be balanced (also known as placement, or trap) include: the temple, the center of the forehead, the back of the neck, the eye socket, the mouth, and the most difficult; the top of the head.
A headroll is an intentional roll of the head around in a semi- or full circle at then end of a turn. Headrolls are often used to embellish simple turns and/or accentuate hits or cues in music. They are commonly practiced in many forms of street dances (e.g. salsa). In partner dancing, one can also lead a follow to perform a headroll during a turn.
