Rude English hand sign that derives from the middle ages. During the 100 years war the French would cut off the middle and index fingers of any English bowman so as they could never shoot again. The English would taunt the French by showing their fingers, so as to say "I can still shoot you Frog!" although todays meaning is more or less "fuck off you twat."
Is the trademark of rock star, Liam Gallagher but was also made popular during the second world war by Winston Churchill where it took on the meaning of V for Victory. It should not be confused with the piss-poor peace sign which is the reverse of it with the palm and fingers facing the viewer instead of the back of the hand.
Due to its historical relevance it should be particularly directed at the French and other historical enemies of the English.
