The gesture of pointing two V-sign fingers at one's own eyes and then at another person to signify "I'm watching you!" is commonly known as "the eyes" gesture or "I've got my eyes on you" gesture. Its origins can be traced back to the United States, specifically to the American military during World War II.
During the war, the gesture was used by soldiers to indicate vigilance and alertness. It served as a way to communicate the message, "I'm watching out for any suspicious or dangerous activity." The gesture was popularized by American soldiers and gained recognition beyond the military, eventually becoming a part of popular culture.
After the war, the gesture found its way into various contexts, including movies, TV shows, and other forms of media. It became a recognizable and often playful way to convey the idea of keeping an eye on someone, either for protective or humorous reasons.
Over time, the gesture has been adopted and adapted by people in different parts of the world and is now widely recognized as a playful way to signify that someone is watching or observing someone else. It is often used in a lighthearted or joking manner, though its origins are rooted in a more serious and vigilant context during World War II.
