The phrase só um tapinha is everyday Brazilian Portuguese for just a little tap, often said jokingly before a light slap or pat. As a soundboard clip it circulates mainly in short-form edits, WhatsApp-style jokes and meme compilations where a small physical action needs a verbal punchline. Its appeal does not depend on knowing a specific song or scene, which helps it travel outside Brazil. Creators reuse it because the wording is catchy, the meaning is easy to guess from context, and the short length fits quick cuts.
