Toi toi toi

"Toi toi toi" (English pronunciation: /ˈtɔɪ ˈtɔɪ ˈtɔɪ/) is an idiom used in opera, and to a lesser extent in theatre, to wish a performer good luck prior to a performance. It is equivalent to the actor's idiom "Break a leg". The expression reflects a theatrical superstition in which wishing a person "good luck" is considered bad luck. The expression is sometimes used outside the opera as superstitions and customs travel through other professions and then into common use.

"Toi Toi Toi" was originally an idiom used to ward off a spell or hex, often accompanied by knocking on wood, and onomatopoeic spitting (or imitating the sound of spitting). Saliva traditionally had demon-banishing powers. From Rotwelsch tof, from Yiddish tov ("good", derived from the Hebrew טוב and with phonetic similarities to the Old German tiuvel "Devil.") One explanation sees "toi toi toi" as the onomatopoeic rendition of spitting three times. Spitting three times over someone's head or shoulder is a gesture to ward off evil spirits. A similar-sounding expression for verbal spitting occurs in modern Hebrew as "Tfu, tfu" (here, only twice), which some say that Hebrew-speakers borrowed from Russian.

An alternate operatic good luck charm, originating from Italy, is the phrase "" ("In the mouth of the wolf") with the response "Crepi!" ("May he [the wolf] die"). Amongst actors "Break a leg" is the usual phrase, while for professional dancers the traditional saying is "merde". In Spanish, the phrase is "mucha mierda", or "lots of shit".
