"Nia pa oh (Here's more)," he said.
He immediately walked away after flashing the dirty finger.
The Finger is identified as the digitus impudicus (impudent finger) in Ancient Roman writings and reference is made to using the finger in ancient Greek comedy to insult another person. The widespread usage of the finger in many cultures is likely due to the geographical influence of the Roman Empire and Greco-Roman civilization. Another possible origin of this gesture can be found in the first-century Mediterranean world, where extending the digitus impudicus was one of many methods used to divert the ever-present threat of the evil eye offence.
The gesture may also be referred to as the highway salute, the Bronx salute, the one-finger salute, the bird (as in giving, flipping, or flying the bird), flipping off someone, or (in Canada) the Trudeau salute.
