Gig acting is a type of performance art in which an actor or actress takes on a ROLE for a short period of time, usually for a single event. It is often used in theater, film, and television, as well as in corporate events and other live performances. The term 'GIG' comes from the phrase 'gigging around, ' which refers to the practice of taking on different roles in different places. GIG acting requires the performer to be flexible and able to quickly adapt to different roles and situations.
