[{"role": "user", "content": "I've come across the phrase 'He went ballistic' and I'm wondering, how would you express that idea in Italian, particularly in a way that conveys the same level of intense anger or reaction?"}, {"role": "assistant", "content": "The phrase 'He went ballistic' is an English idiom that means someone has become extremely angry or upset. In Italian, you can convey the same idea by saying 'Lui ha perso le staffe.', which literally means 'He lost his stirrups,' but figuratively means he lost control of himself."}]
