Não vai dar não is everyday Brazilian Portuguese for it is not going to work, a blunt refusal that is instantly understood even by listeners who do not speak the language. As a short audio, it circulates mainly through Brazilian meme pages, gaming clips and chat audio sharing, where a single spoken line can carry a whole reaction. Its popularity comes from that flexibility: the same phrase can reject a dare, mock a bad strategy or predict failure before it happens. Because it is so brief, it slots easily into edits without breaking the pace.
