The "🤘🏼" emote, also known as the "Sign of the Horns: Medium-Light Skin Tone" emote, is a hand gesture made by extending the index and little fingers while holding the middle and ring fingers down with the thumb. It is commonly used to signify rock music or to express enthusiasm, approval, or solidarity. The emote was added to the Unicode Standard in 2016 and is available on most platforms.
