Flamengo, based in Rio de Janeiro, is one of Brazil's most popular and successful football clubs, which makes any defeat a major talking point online. The phrase Flamengo perdeu is plain Portuguese for Flamengo lost, and rival supporters repeat it whenever the team is beaten. Short clips built around losses circulate on social media, messaging apps and fan edits after big matches, especially derbies and cup upsets, turning a normal result into shared banter that returns every season.
