'Lá vem o Marcos!' circulated online as a short Brazilian meme audio built entirely around its own catchphrase, the shouted warning that Marcos is coming. Because the name and delivery are so specific, users repurposed it far beyond anyone actually called Marcos, applying it to friends, pets, teachers and fictional characters making an entrance. Its brevity helped it spread in short form videos, soundboards and chat audios, where it works instantly without context or explanation, and it remains a go to entrance joke in Portuguese speaking meme culture.
