The term 'two-finger gesture' is often used to describe the V-sign, which is a hand gesture made by holding up the index and middle fingers in a V-shape. It is commonly used as a sign of peace or victory, and is also known as the 'victory sign' or 'peace sign'. The V-sign is believed to have originated in the United Kingdom during World War II, when it was used as a symbol of defiance against Nazi Germany.
