Galvão Bueno is one of Brazil's best-known football commentators, famous for his emotional, high-energy narration of major matches on Brazilian television. Acabou is Portuguese for it is over, and it is the natural word for a commentator to shout when the final whistle blows and a result becomes official. Short clips of that moment have circulated widely in Brazilian football and meme communities, where the shout is detached from any single match and reused as a universal signal that something has ended, whether a game, a debate or a joke.
