Short name call reactions like this circulate widely in Brazilian meme culture, where brief WhatsApp audios and soundboard clips are reused far beyond their first context. The appeal here is the familiar Oxi interjection paired with a specific name, which makes an ordinary surprise feel personal, as if Luciana herself has just done something unbelievable. That specificity is what makes it funny when applied to strangers, pets or fictional characters. Clips this short spread easily because they can be saved, replayed and inserted into almost any edit without explanation.
