The sound comes from Team Four Star's Dragon Ball Z Abridged Kai, the fan-made parody series that re-edited and re-voiced Dragon Ball Z with fast, sarcastic humour. Lines like this one spread through gaming clips, reaction videos and meme edits because they sound exactly like what viewers are already thinking during a bad play. Even outside Dragon Ball fandom, the question works on its own, needing no context to understand that someone should have moved, which is why editors keep returning to it for fails and missed dodges.
