The phrase comes from Mexican Spanish slang, where valió verga is a vulgar expression for something being completely ruined or lost. Online, Spanish-speaking users attached it to Scooby-Doo because the cowardly cartoon dog is famous for stumbling into monsters and traps, making him a perfect mascot for doomed situations. Short clips using the line circulated on meme pages and messaging apps as a reaction sound, and it remains popular in Latin edits where a character realizes too late that trouble has already found them completely.
