Why wish someone 'good luck' when you can use this Italian phrase instead? AdvertisementLiterally translating into English as 'in the wolf's mouth', this famous Italian phrase (hear it pronounced here) is much more interesting to say than a simple 'good luck'. The phrase andare nella bocca del lupo, or 'to go into the wolf's mouth' means metaphorically 'to get into trouble'. AdvertisementSome even believe the idea of ending up in a wolf's mouth has positive connotations, since wolves protect their young by carrying them in their mouths. In general though, the easiest response to in bocca al lupo is always crepi.
