O Zé is a user generated Portuguese soundboard clip built entirely around one shouted name, with the published description simply reading o joão. That pairing tells the story: it is a joke for people named Zé or José, a playful call used to tease, greet or summon someone in memes and chat groups. Like many WhatsApp and soundboard favourites in the Portuguese speaking internet, it spread because it is short, personal and infinitely reusable rather than because of any single source video.
