The dai mooooo sound circulates as a short standalone reaction clip rather than a scene people quote from a known film or show. Its appeal is the simple, recognisable moo stretched far beyond a normal animal sound, which makes it easy to recognise even without any visual context. Shared in chats and short videos, it has become a last-resort joke, saved for moments when words are not enough and a silly noise works better. That low-context humour helps it travel between different audiences and edits.
