The phrase was popularised by the 2001 comedy film Zoolander, where it was used to describe a model at the peak of his fame, and it stuck because it sounded both admiring and faintly absurd. As short-form video grew, creators lifted the line as a standalone reaction sound for anything suddenly fashionable, from outfits and hairstyles to gadgets and celebrities. Its brevity makes it easy to drop into edits, and its ironic, fashion-world tone still works today because it can praise something sincerely while also poking fun at hype itself.
