. The “Fig” 'I've got your nose'. Nothing more than a fist with the thumb poking out from between the index and middle fingers, the mano fico (literally ‘fig hand’) is a gesture of Roman origin, used as a positive gesture to encourage good luck and fertility, and ward away the ‘evil eye’. The sexual nuance comes from from the hand’s resemblance to the female private parts (fica is actually Italian slang for “vulva”), with the nub of the thumb representing the clitoris. There seems to be a lack of positive meaning to this sign these days, however. If you’re doing the ‘fig’, it probably means you’re denoting a letter T in American Sign Language. But if somebody else is giving you the same gesture (especially if they are of the Asian persuasion), they’re probably giving you a rather disparaging insult, roughly equivalent to “f--- you!”. This hand sign is also highly disparaging to Italians and Turks, and in India would be taken as a threatening gesture. Most non-deaf Americans or Brits, however, would simply see the mano fico as a bizarre-looking fist.
So it's a Macaca Moment???

The “mano fico” is the letter “T” in American Sign Language. In most Central and South American countries it is equivalent to “f-— you!”. This has been discovered by many ASL-101 graduates, much to their embarrassment.
