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.
