Meaning
A hand raising the index and middle fingers in a V, palm facing outward. It can mean peace, victory or simply a cheerful, laid-back vibe, and it is a classic pose in group photos and selfies.
Use it for a relaxed goodbye, a small win or a carefree mood: “Last exam done, summer starts now ✌️” Its exact shade depends on the reader, since some see “peace out” and others see “we won.” In the UK and a few other places the reversed gesture with the palm inward is offensive, but the emoji shows the friendly version.
