Rhosgobel is the forest home of Radagast the Brown in Tolkien's Middle-earth stories, and rabbits are closely linked to the wizard in modern adaptations, where he is shown travelling with them through the woods. That association has made the name a shorthand for gentle, woodland fantasy among fans, and short rabbit sounds labelled with it now circulate on soundboards for use in edits, streams and memes. Creators keep returning to it because it instantly sets a rustic, magical mood without needing dialogue or a recognisable musical cue.
