The sound comes from the long-running TV game show Family Feud, where a loud buzzer and red X mark an incorrect survey answer. Clips of the buzzer spread online as a universal shorthand for a wrong answer, far beyond the show itself. Creators now use it in trivia videos, classroom edits, and meme compilations whenever someone gives a confidently bad guess, which is why it remains a staple game show sound effect alongside a correct answer gameshow chime.
