What is metal handsign?

Metal handsigns are hand gestures commonly used in heavy metal culture to express allegiance, appreciation, or approval. These hand signs are often accompanied by raised fists, making the gesture even more powerful and energetic. Some of the most popular metal handsigns include the horns (also known as the devil horns or the metal horns), the index and pinky finger extended, and the thumb extended, forming the letter "L" in American Sign Language, symbolizing love. Another popular metal handsign is the inverted horns, where the same gesture is made but with the hand facing down. Metal handsigns have become a part of metal culture, with artists and fans using these gestures during concerts and festivals to show solidarity and appreciation.
