Slur for southern Italians. A terrone is exactly the stereotypical wop.
Insult widely used by northern Italians to call those living in the southern (some would even say mid-south) part of Italy.
Terrone: "We got the sun, pizza, spaghetti and the sea! beautiful italia!"
Northern Italian: "You lowlife terrone! Go back south!"
"i'm from napoli" - paolo
"oh so your a terrone?" - massimo
"ma vaffanculo, brutto stronzo" - paolo
