The clip comes from Metalocalypse, the animated series centred on a fictional metal band and its outsized commercial world, and it is taken from the intro for Dunkin Hills Coffee, the show's fictional coffee brand. Short jingle intros like this travel well online because they are instantly recognisable, easy to drop into a video, and funny even without the surrounding episode. Coffee creators, morning routine editors and meme makers keep reusing it as a quick, self-contained opener that signals caffeine, routine and playful exaggeration in just a few seconds.
