Galvão Bueno is Brazil's best known sports broadcaster, famous for his emotional narration of football matches for TV Globo across decades of World Cups and major finals. His drawn out call of acabou, meaning it is over in Portuguese, became a recognisable signature whenever a game reached its conclusion. Clips of the shout later spread beyond broadcasts through Brazilian social media and messaging groups, shortened into a standalone reaction. It remains popular because the voice alone signals a dramatic ending, even for situations far removed from sport.
