Anatomical terminology

In Western countries, extending the middle finger (either by itself, or along with the index finger in the United Kingdom: see V sign) is an offensive and obscene gesture, widely recognized as a form of insult, due to its resemblance of an erect penis,[1][2] It is known, colloquially, as "flipping the bird",[3] "flipping (someone) off", or "giving (someone) the finger". Similarly, one may extend the middle, ring and pointer fingers to someone and say "read between the lines."[citation needed]

The middle finger is often used for finger snapping together with the thumb.
