So aside from keeping your hands firmly in your pockets while you are traveling, what can you do to ensure that you don’t insult the locals or end up in a bar brawl? The last time I checked, there was no section in any of my phrasebooks for hand gestures.
1. The chin flick. Brushing the back of your hand underneath your chin in a flicking motion means “get lost” in Belgium, northern Italy, and Tunisia. In France, this gesture is known as la barbe (”the beard”) and is the hand-sign equivalent of macho grandstanding.
