The phrase plays on the famous catchphrase of Brazilian television host Fausto Silva, known as Faustão, whose energetic greetings became part of Brazilian pop culture through his long-running Sunday variety show. The diminutive 'Olokinho' and the 'zinho' nickname turn that larger-than-life presenter style into something smaller, cuter and more playful, which is why the clip works so well as a meme. Shared as a short audio snippet on soundboards and in short-form videos, it is now used far beyond its television roots as a quick, affectionate way to greet, tease or introduce someone.
