Lucha libre is the term for the style of professional wrestling originating in Mexico. Since its introduction to Mexico in the early 20th century, it has developed into a unique form of the genre, characterized by colorful masks, rapid sequences of holds and maneuvers, and "high-flying" maneuvers, some of which have been adopted in the United States, Japan, and elsewhere. The wearing of masks has developed special significance, and matches are sometimes contested in which the loser must permanently remove his mask, which is a wager with a high degree of weight attached. Tag team wrestling is especially prevalent in lucha libre, particularly matches with three-member teams, called trios.

Professional wrestling is a form of athletic theater that combines mock combat with drama, under the premise that the performers are competitive wrestlers. Although it entails elements of sports wrestling and martial arts, including genuine displays of athleticism and physicality before a live audience, professional wrestling is distinguished by its scripted outcomes and emphasis on entertainment and showmanship. The staged nature of matches is an open secret, with both wrestlers and spectators nonetheless maintaining the pretense that performances are bona fide competitions; this is likened to the suspension of disbelief employed when engaging with fiction.
