business or biz
- In theatrical parlance, a piece of incidental action or by-play carried out for dramatic or comic effect. In practice, it is often used to distract the audience's attention from the actor who is supposed to be the focal point of the scene. Business usually takes the form of fiddling with a prop or part of a costume. It is generally the creation of the actor who plays the part, although certain pieces of business have been handed down by tradition. The term is a shortened form of stage business. Comedians often refer to physical falls and feats as business or knockabout business.
