Show do Milhao is the Brazilian version of the millionaire quiz format, broadcast by SBT and famously hosted by Silvio Santos from 1999. On the show, contestants answered questions against the clock for a large cash prize, and the tempo acabou line marked the moment their thinking time ended. Clips from Brazilian television spread widely on soundboards and in meme edits in Portuguese, where the phrase became shorthand for any expired timer, missed chance or last second failure in games and everyday situations.
