The phrase comes from Brazilian internet slang, where isso me estressa is a blunt way to say something is getting on your nerves. The OLendari0 version spread as a reusable reaction clip because the wording is short, familiar, and easy to recognize out of context. Online, it is treated less like a quote needing setup and more like a soundboard button for stress, similar to other short reaction sounds used in edits. Its appeal is the mix of everyday Portuguese and over the top delivery, which travels well across gaming and meme videos.
