The exact origin of Gandalfdhino is not documented, and the title appears to come from user generated soundboard uploads rather than an official release. Clips with invented or mashed up names like this spread mainly through reposts, gaming chats and short video edits, where the name itself becomes the search term people share. Its appeal has less to do with a known scene and more with repeat use as a recognisable in joke, so new listeners find it through friends, streams and compilations instead of a single source.
