There are many recognised meanings to the symbol of Mano Fico, including slang connotations.
The Mano Fico, also called fig sign, is a mildly obscene gesture used in Turkish and Slavic cultures and some other cultures that uses two fingers and a thumb. This gesture is most commonly used to deny a request.
In Brazil, use of this gesture is said to ward off evil eye, jealousy, etc. Ornaments with this symbol are often worn as a good luck charm.
Among early Christians, it was known as the manus obscena, or "obscene hand"
Ancient Greeks used the word “fig” as slang for the female genitalia so the gesture is often thought to represent sexual intercourse. Some Roman amulets combine a phallus and a mano fico gesture.
