A "jinx" is a type of curse or spell that is believed to bring bad luck or misfortune to a person or situation. Often associated with superstitions, jinxes can be invoked through specific words, actions, or rituals. People may use the term casually, such as when someone says "You jinxed it!" after a negative event occurs. In popular culture, jinxes are often depicted in movies, books, and games, where characters may cast or fall victim to them. The concept is closely related to other forms of magic and folklore, including hexes, spells, and superstitions.
