The phrase comes from A Grande Família, the popular Brazilian television sitcom centred on a working-class family in Rio de Janeiro, where exaggerated everyday arguments and declarations became part of its humour. Clips from the show have circulated widely as short audio memes, shared on social media and soundboards by Portuguese-speaking viewers who recognise the tone instantly. 'Hoje vou me acabar' has survived as a standalone reaction because its meaning is flexible, covering partying, eating, spending, or simply giving in, while still sounding unmistakably Brazilian and comic.
