Quali sono alcune espressioni colloquiali utili in italiano?
I am an English speaker who will be visiting Italy soon and attending a language school. I'm hoping to meet other people around my age there (early 20s). What are some useful expressions that young Italians use in casual conversation? I'm looking for equivalents to things I would say in English, like 'cool,' 'dude,' 'what's up,' 'oh my gosh,' etc., but also things I may not use which are common in Italy.
Thanks for your help!
