Culiao is a Chilean slang term used as an insult, a teasing nickname and, depending on tone, an exclamation of surprise, and this clip leans into that last use by stretching the final vowel into a comic shout. Short meme audios like this travel through soundboards, short-form videos and chat groups, where a single recognisable word can stand in for a whole reaction. Its appeal is partly linguistic and partly performative: listeners who know the slang hear the attitude instantly, while everyone else hears the exaggerated emotion. That combination keeps it in rotation for reaction edits.
