Little is publicly documented about the original source of Hok Co Peo, so it is best understood as a user-shared soundboard clip rather than a line tied to a known show, film or song. Its appeal online comes from brevity and repeatability: at well under a second, it is easy to reuse, remix and drop into fast-paced edits without interrupting the flow. That portability has helped it survive as a small, quirky reaction sound, passed between creators who want a quick, light-hearted accent rather than a long, recognisable quote.
