The line comes from Esperando la Carroza, the 1985 Argentine comedy built around a chaotic family wake, and is tied to the performances of Luis Brandoni and China Zorrilla. In Argentine slang, calling someone falluta means branding them treacherous or two-faced, which is why the insult survived far beyond the film. It circulates online as a WhatsApp audio and meme reaction, dropped over gossip clips, betrayal edits, and reality TV moments where someone is caught being fake.
