Keyboard banging has no single famous source, which is part of why it works so widely: it is a generic, instantly readable sound effect rather than a quote from one show or game. Online it appears in gaming clips, reaction videos, office skits, and meme edits whenever a character is shown typing furiously, losing an argument in chat, or watching something go wrong on screen. Because the gesture needs no explanation, creators keep reusing it as shorthand for frustration, impatience, and comic overreaction in very short videos.
