The phrase comes from Spanish internet slang combined with Ben 10, the animated series that premiered in 2005 and introduced the Omnitrix, the watch like device Ben Tennyson uses to transform into aliens. Saying someone 'traes el Omnitrix' became a joking way to say they are carrying something powerful or enviable. The line spread as a short audio meme across Spanish speaking social media and messaging apps, where it is now used far beyond cartoon fandom as a quick, recognisable reaction to any impressive reveal or flex.
