'Mamma mia!' is a genuine Italian exclamation of surprise, not just a cliché. 'Mamma' is arguably the most affectively loaded word in the Italian language, deeply tied to Italian cultural identity.
Mamma mia, che sorpresa!
My goodness, what a surprise!
La mamma prepara sempre qualcosa di buono.
Mum always makes something delicious.
