What it means
Good luck. The conventional reply is crepi il lupo ('may the wolf die') or simply crepi — replying grazie is considered to invite bad luck.
Literally: Into the wolf's mouth.
Examples with translations
In bocca al lupo per l'esame!
Good luck with the exam!
—In bocca al lupo. —Crepi!
'Good luck.' 'Thanks!'
Note: The exchange is fixed. Answering 'grazie' marks you as a foreigner.
Where it comes from
The logic is the same as English 'break a leg': wishing good luck directly is thought to jinx it, so you invoke the danger instead. A minority argue the wolf's mouth is protective, as a she-wolf carries her cubs — in which case crepi il lupo is a mistake. Italians argue about this.
