About this sound
A very short spoken clip in Italian repeating the line questo c'ha la faccia da tradi, delivered like a playful accusation pointed straight at someone. It lands as teasing and suspicious rather than angry, turning an ordinary look or excuse into a funny call-out that everyone in the group instantly understands as a joke.
