The phrase is common Spanish for saying that something will settle or become stable, which is why it travels so well in short-form memes even for viewers who do not speak the language: the tone does the work. Online, it is shared as a reaction sound for moments of panic, bad decisions, and escalating chaos, where a confident voice promising stability becomes the joke itself. Its appeal is that contrast, and it keeps appearing in edits because almost any disaster can be captioned with the same calm assurance.
