The origin of Thomas met baby olie is not clearly documented, and the clip circulates mainly as a standalone soundboard sound rather than as a clip tied to a known film, song or show. Its appeal online comes from that lack of context, with the plain Dutch phrasing making it easy to reuse as an inside joke. It has stayed in use as a short random humor sound, shared in chats and edits where an unexplained reference to Thomas and baby oil is funnier than an explained joke.
