To us, we think of this jesture as a way of saying “no more”, “stop”, or even “i’m busy”. Even though we mean it in a harmless way, people in Greece mean it as something much worse. There, putting your hand out is a gesture known as the moutza. When you do this it is interpreted as yousaying that there faces are going to be covered in human waste. The gesture dates back to the Byzantine Empire, where crimals would be paraded though the streets with blackened faces. Usually, the black was something as simple as charcoal, but if your were unlucky it could be something a lot worse. Instead of being a harmless gesture here, it is a rude insult there.
