Because the phrase works out of context, the clip spread as a reusable reaction for moments where opening something creates instant regret. Editors use it for package reveals, game loot, leaked screenshots, and horror edits where a sealed door, box, or file should have stayed closed. Its appeal is the deadpan hindsight: instead of screaming, the speaker states the obvious lesson after it is too late. That understated tone lets it fit comedy, gaming, and meme edits without needing any setup or explanation beforehand.
