Bad to the Bone was released by George Thorogood and the Destroyers in 1982, and its opening riff became one of the most recognizable bits of blues rock in popular culture. The song appeared in films, TV and ads for decades, which helped turn the intro into a shorthand for rebellion, swagger and tongue-in-cheek badness. Online, creators often isolate just the first second or two for quick meme edits, especially when they want an exaggerated tough-guy reveal or a knowingly overdramatic entrance.
