Get the fuck outta here! 

Often heard in movies where the characters are Italian Americans living in New York.

It simply means that you don't believe what someone else said.

Henry Hill: There it is, you see that Mike? You see that Helicopter? See it right there, right infront of us there? I think it's been following me all morning.

Mikey: Get the fuck outta here! What are you, nuts?
