Growing up, my cousins were a bit older than me. They knew all the curse words in Italian by heart.
They would give us younger ones money if we would run into the kitchen and yell them out as loud as we can in front of all the grandmas and aunts cooking.
When you are 5 or 6, vafanculo usually came out like; "Bah-Svengoolie!"
(Svengoolie was a late night horror movie host on the weekends in Chicago)
