The phrase comes from everyday Chilean Spanish, where oe is a casual hey, paca is a shortened form of para aca, meaning over here, and altiro means right away. Together they form a blunt, familiar summons used between friends rather than a formal request. As a short soundboard clip, it circulates mainly as a reaction sound for calling someone over, cutting to a late arrival, or interrupting a scene with an urgent shout. Its appeal lies in the slang itself, which gives Spanish-language memes and videos a local, streetwise flavour that a neutral translation would lose.
