Ace Attorney is Capcom's courtroom visual novel series, first released in Japan in 2001, starring defence lawyer Phoenix Wright cross-examining witnesses to find contradictions. Its short dramatic stings became meme shorthand online, shared in edits much like the dun dun dunnnnnnnn sting for a shocking reveal. Fans clipped this realisation cue from gameplay and reused it in YouTube and TikTok videos whenever someone in real life noticed a lie, a mistake, or a detail everyone else had missed, turning a courtroom cue into a universal reaction sound.
