The exact original recording is unclear, but the clip circulates as a Brazilian Portuguese group-chat greeting, the kind of short voice note people forward to mark the start of the evening. Its popularity comes from being instantly recognizable to Portuguese speakers and easy to reuse: one quick interruption, one friendly good night. It belongs to the same wave of short Brazilian chat greetings as bom dia magnata, and it is often saved alongside other funny voice notes people forward in groups.
