The phrase behind this clip is Brazilian Portuguese for 5 plus 5 plus 5 plus 5, that is very easy, and its humour comes from treating basic addition as a dramatic achievement. Shared as a short meme sound, it fits the style of reaction audio that creators reuse across edits, shorts and group chats whenever a task is presented as hard but turns out to be trivial. Its short length and clear repeated numbers make it easy to recognise, quote and drop into a punchline without needing any context, which helps explain why it keeps appearing in comedy edits.
