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.

An obscene gesture is a movement or position of the body, especially of the hands or arms, that is considered exceedingly offensive or vulgar in some particular cultures. Such gestures are often sexually suggestive.
