In Brazil, before the hand sign became Americanized to the single finger salute, the "figa" (balled fist with thumb protruding between index and middle fingers) was sometimes used to express the more vulgar sentiment. Its use stemmed from a symbol of fertility that became part of the Brazilian culture by way of slaves imported from Africa. Beautifully carved figas are still worn on necklaces and bracelets by many people from all walks of life. Apparently, the original significance is portrayed in this form; whereas the more vulgar meaning seems only to be transmitted by the use of the hand signal - although it is rarely used these days.
