The clip comes from a collection of funny moments recorded from the YouTube channel Manuel Sousa, where short caught-on-camera reactions were shared as Portuguese humour clips. The name Carolina points to the woman heard in the recording, while the coarse phrase she uses is a familiar Portuguese expression of surprise. Shared on soundboards, it spread among Portuguese-speaking meme makers who reuse brief, expressive reactions to punctuate edits, keeping it alive as a compact shorthand for disbelief.
