The (Middle) finger
Synonymous with various phrases revolving around a verb that begins with the letter F, the middle finger is one of the most universally recognized and reviled gestures in history. Made particularly popular by late 20th century rock and punk personalities as a sign of rebellion and anti-establishmentarianism, the finger today is used liberally by people of all ages.

The finger dates all the way back to ancient Greece when it was meant as an insult, suggesting that the recipient of the gesture would easily submit to anal intercourse. By the Roman era, the middle finger had garnered the superstitious trait of being indecent, and is seen in Roman literature as an act of ill-intention and tool of black magic.

The first known occurrence was in 66 CE, when a Roman soldier mooned passing Jewish pilgrims during Passover, causing a riot and subsequently a military response that killed thousands. Bearing one’s buttocks in provocation has been a favorite particularly in English-speaking countries since the colonial era, although it did not earn its lunar moniker until the 1960’s when American college students popularized it through protests. Today, it is a leading cause of fines against footballers and a ritual of irreverent weirdness for several thousand thrill-seekers during the annual Mooning of Amtrak.

It has many names across the world, the banana, the umbrella, the sleeve-cut, but its meaning is graphically clear: “Shove it as far as your arm can reach.” Chances are you’ve known this gesture for years and have even thrown it a few times without being aware of it. French for “arm of honor” (they give The Finger the same distinction), its origin also dates back to the 100 Years War, used by the French to intimidate their hated English rivals.
