This clip circulates as a WhatsApp audio attributed to Lucas, whose extended paoo became a small in-joke among friends who shared it onward as a reaction sound. The tag oveja, Spanish for sheep, points to why listeners find it funny, since the stretched vocal resembles a bleat more than a word. Like many short WhatsApp audios, it spread informally from chat to chat rather than through a television show or song, and it survives because it is instantly recognisable, easy to drop into a reply, and absurd enough to break the tone of a normal conversation.
