A catchphrase (or 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 a variety of mass media (such as literature and publishing, motion pictures, television and radio), as well as word of mouth. Some become the de facto "trademark" or "signature" of the person or character with whom they originated, and can be instrumental in the typecasting (beneficially or otherwise) 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.

Willard Christopher "Will" Smith, Jr. (born September 25, 1968), also known by his stage name The Fresh Prince, is an American actor, producer, and rapper. He has enjoyed success in television, film and music. In April 2007, Newsweek called him the most powerful actor in Hollywood. Smith has been nominated for four Golden Globe Awards, two Academy Awards, and has won multiple Grammy Awards.

In the late 1980s, Smith achieved modest fame as a rapper under the name The Fresh Prince. In 1990, his popularity increased dramatically when he starred in the popular television series The Fresh Prince of Bel-Air. The show ran for nearly six years (1990–1996) on NBC and has been syndicated consistently on various networks since then. In the mid-1990s, Smith moved from television to film, and ultimately starred in numerous blockbuster films. He is the only actor to have eight consecutive films gross over $100 million in the domestic box office and the only one to have eight consecutive films in which he starred open at #1 spot in the domestic box office tally.
