Listed in Portuguese as inicio and fim de cena, this clip is best understood by its function rather than a single famous source: it marks where a scene begins and ends. Short transitional sounds like this circulate widely among editors because they can be reused across unrelated videos without carrying a recognisable joke or character with them. That flexibility is why it fits sketches, vlogs and social edits alike, where a brief framing cue can turn loose footage into something that feels deliberately staged and complete.
