Bad to the Bone is a 1982 blues-rock song by George Thorogood and the Destroyers, best known for its driving opening guitar riff. Over the decades it became a shorthand for toughness and cool confidence in films, television and advertising, often playing as a character makes a bold entrance. On social video and meme edits, that same short riff is now reused as a quick audio cue, instantly signalling attitude without needing any dialogue or explanation.
