The phrase comes from Luis Caputo, Argentina's economy minister under President Javier Milei, who in 2025 challenged critics of the official exchange rate to buy dollars if they thought the peso was overvalued. His compra campeon taunt was clipped from interviews and shared widely on Argentine social media, news memes and WhatsApp groups. It quickly became shorthand for dismissing economic pessimism, used both by supporters celebrating the remark and by critics mocking it whenever the dollar moved.
