There is no widely documented source for this clip, so it is best understood as a short Portuguese soundboard announcement rather than a line from a known show or film. The phrase itself simply announces an arrival, which is why it travels well across different kinds of content: the listener does not need much context to understand that something is about to happen. Its under-six-second length also fits the quick cuts of short-form video, where a single spoken teaser can set up a joke, entrance or reveal without slowing the edit down.
