The phrase comes from Brazilian internet humour, where clips associated with Tiririca, the famous clown turned politician, are widely shared as reaction sounds. This version is known on soundboards by its misspelled title Eu vo morreeeeee, reflecting how the word is screamed and stretched in the audio itself. It spread through shares, remixes and short video edits rather than a single film or TV scene, and remains popular because the panic is instantly understood even by viewers who do not speak Portuguese, making it a reusable punchline for fake tragedy.
