The phrase comes from Chilean Spanish slang, where guatona is a rude word for a fat woman and qla is a shortened vulgar intensifier, with fea meaning ugly. No single film, show or creator is reliably credited for this clip, and it circulates mainly as a loose soundboard and messaging audio. It spread through Spanish speaking meme pages and short videos as a quick insult reaction, kept alive because the short length and harsh delivery make it easy to reuse in roasts and edits.
