A catchphrase (alternatively spelled catch phrase) is a phrase or expression recognized by its repeated utterance. Such phrases often originate in popular culture and in the arts, and typically spread through word of mouth and a variety of mass media (such as films, internet, literature and publishing, television and radio). Some become the de facto or literal "trademark" or "signature" of the person or character with whom they originated, and can be instrumental in the typecasting of a particular actor.
According to Richard Harris, a psychology professor at Kansas State University who studied why people like to cite films in social situations, using film quotes in everyday conversation is similar to telling a joke and a way to form solidarity with others. "People are doing it to feel good about themselves, to make others laugh, to make themselves laugh", he said. He found that all of the participants in his study had used film quotes in conversation at one point or another. "They overwhelmingly cited comedies, followed distantly by dramas and action adventure flicks." Horror films, musicals and children's films were hardly ever cited.
