The line comes from 'O Que Sobrou do Céu' by Brazilian band O Rappa, whose music blends rock, reggae and Brazilian rhythms. Taken out of context as a three-second snippet, the lyric about losing power during the day travelled online as a compact reaction sound for blackouts, faulty wiring and ironic complaints about electricity. Its staying power comes from how instantly recognisable the situation is in Brazil and beyond: everyone has experienced a sudden outage, and the daytime twist makes the frustration feel funny rather than merely annoying.
