The phrase comes from the Latin Spanish dub of The Simpsons, where Bart Simpson uses antes eras chevere to tell someone they have changed for the worse. Clips and screenshots of the scene spread widely on Latin American social media, WhatsApp groups and meme pages, where the line became shorthand for nostalgic disappointment. It is now used far beyond Simpsons fans, posted as a standalone audio or caption whenever a person, brand, series or trend is seen as less cool than it once was.
