The "🤘🏼" emote or "Sign of the Horns, Type-3" emote is a hand gesture that involves extending the index and pinky fingers while tucking in the middle and ring fingers, forming a horn-like shape. It is commonly used to signify rock music or heavy metal culture, but can also be used as a general symbol of excitement or approval. The emoji was added to Unicode in 2016 and is available on most platforms.
