Hi, it's not about me making an embarrassing mistake, but in Italian culture, there is this one thing that I feel awkward about whenever it happens.
When people drink together, I hear people say "toast!" or "Cheers!" in English. In Japan, they would say "Kanpai" and here in Italy, the most common word is "cin cin". If you are Japanese, I assume you are laughing right now because as you know, "cin cin" means "penis" in Japanese.
Every time my family and my friends say "cin cin" with a big smile on their face, I don't know what I have to do.
