The finger [SEP] Introduction
In Western culture, "the finger" or the middle finger (as in giving someone the (middle) finger or the bird or flipping someone off) is an obscene hand gesture. The gesture communicates moderate to extreme contempt, and is roughly equivalent in meaning to "fuck me", "fuck you", "shove it up your ass/arse", "up yours" or "go fuck yourself". It is performed by showing the back of a hand that has only the middle finger extended upwards, though in some locales, the thumb is extended. Extending the finger is considered a symbol of contempt in several cultures, especially in the Western world.
