Friday the 13th is an American horror franchise that comprises twelve slasher films, a television show, novels, comic books, and tie‑in merchandise. The franchise mainly focuses on the fictional character Jason Voorhees, who drowned as a boy at Camp Crystal Lake due to the negligence of the camp staff. Decades later, the lake is rumored to be "cursed" and is the setting for a series of mass murders. Jason is featured in all of the films, as either the killer or the motivation for the killings. The original film was written by Victor Miller and was produced and directed by Sean S. Cunningham. However, neither returned to write or direct any of the sequels. The films have grossed over $465 million at the box-office worldwide.

The first film was created to cash in on the success of Halloween (1978), and its own success led Paramount Pictures to purchase the full licensing rights to Friday the 13th. Frank Mancuso, Jr., who produced the films, also developed the television show Friday the 13th: The Series after Paramount released Jason Lives. The television series was not connected to the franchise by any character or setting, but was created based on the idea of "bad luck and curses", which the film series symbolized. While the franchise was owned by Paramount, four films were adapted into novels, with Friday the 13th Part III adapted by two separate authors. When the franchise was sold to New Line Cinema, Cunningham returned as a producer to oversee two additional films, in addition to the crossover film with Freddy Krueger from the Nightmare on Elm Street film series. Under New Line Cinema, 13 novellas and various comic book series featuring Jason were published.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
