The phrase comes from Capcom's Phoenix Wright: Ace Attorney series, where lawyers and prosecutors shout objections during courtroom cross-examinations to challenge testimony. Miles Edgeworth, the cool and precise rival prosecutor, uses the line when he exposes a flaw in a witness's statement. As clips from the games spread through Let's Plays, edits and meme soundboards, the short shout became a shorthand for a decisive rebuttal online. It remains popular because it is instantly recognisable to fans and works even for viewers who have never played the games.
