A barker is a person who attempts to attract patrons to entertainment events, such as a circus or funfair, by exhorting passing public, describing attractions of show and emphasizing variety, novelty, beauty, or some other feature believed to incite listeners to attend entertainment. A barker may conduct a brief free show, introducing performers and describing acts to be given at the feature performance. Professional barkers strongly dislike the term and instead refer to themselves as "talkers."
