The phrase comes from everyday Brazilian Portuguese slang, where passando mal can mean feeling sick but is often used hyperbolically to say something was too funny, too cringe or too shocking to handle. Clips stretching the last word became a staple reaction sound in Brazilian meme pages, WhatsApp groups and short video edits, shared as a quick audio shorthand for losing control laughing. Its popularity relies on that double meaning, letting creators pretend a joke physically hurt them, which keeps it circulating as a go to reaction in Portuguese speaking online humour.
