The greeting is associated with Boris Casoy, a well-known Brazilian television journalist whose calm sign-off became familiar to nightly news viewers in Brazil. As the clip circulated on soundboards and social media, Brazilian creators adopted it as a shorthand goodnight, detached from any single broadcast and instantly understood by Portuguese-speaking audiences. Its staying power comes from that familiarity: it sounds authoritative yet warm, so it works both sincerely at the end of a video and ironically after a joke, keeping a piece of classic Brazilian television alive in short-form edits.
