What it is
"In bocca al lupo" is an Italian idiom used to wish someone good luck, particularly before a performance. It translates literally to "into the wolf's mouth." The phrase stems from a theatrical superstition where wishing luck directly is thought to invite misfortune. Instead, speakers invoke a dangerous situation to trick fate. The customary reply is "crepi il lupo," which means "may the wolf die," or simply "crepi." While rooted in opera and theatre, the expression has spread beyond the stage into everyday conversation in Italy and occasionally abroad.
Where it comes from
The practice likely began among hunters who wished each other entry into dangerous situations rather than offering simple good wishes. This negative phrasing was believed to ward off bad luck. The wolf serves as a symbol of danger, hunger, and violence in Western culture and Italian language. Similar customs exist in other languages, using negative or taboo subjects to achieve the opposite result. The custom evolved from hunting traditions into the performing arts, where the risk of failure made such superstitions common.
How it is done
The interaction involves two people. One person says "in bocca al lupo" to wish the other success. The recipient responds with "crepi il lupo" or "crepi," effectively wishing the wolf dead. This exchange replaces the direct phrase "good luck." In some contexts, similar customs involve knocking on wood or imitating spitting sounds to break a spell. The ritual relies on the spoken words and the shared understanding of the underlying superstition.
