☞ Fig sign - Offensive hand gesture

The fig sign is a mildly obscene gesture that uses a thumb wedged in between two fingers. The gesture is most commonly used to ward off the evil eye, insult someone, or deny a request. It has been used at least since the Roman Age in Southern Europe and parts of the Mediterranean region, including in Turkish culture. Some countries in Asia, Slavic cultures and South Africa use it too. It is used playfully in Northwestern Europe and North Africa, countries such as the US, Canada, Australia, Libya, Tunisia and Czech Republic to pretend to take the nose off a child.
