João Kleber is a Brazilian television presenter who became a familiar face on Brazilian daytime TV, best known for hosting variety and relationship-themed programmes that became talking points in Brazil. The word vinheta means a short television jingle or opening sting, and clips labelled with his name circulate online as ready-made intros. Creators reuse them because the sound instantly evokes classic Brazilian TV, giving even a short meme or edit a broadcast-style opening without needing a full theme song.
