Hodor is the gentle giant from Game of Thrones, a character famous for speaking only one word, his own name, a trait later explained by the phrase hold the door. That single-word vocabulary made him an easy target for fan remixes, and this opening-style version turns his chant into a mock theme tune. Shared on soundboards and in meme edits, it works because anyone who knows the show recognises the joke instantly, while newcomers still enjoy the absurd, rhythmic repetition.
