Himouto! Umaru-chan originates from the manga and subsequent anime series featuring Umaru Doma, a character who leads a double life as a refined high schooler and a couch-potato otaku. The meme templates typically feature her chibi form wearing her signature orange hamster hoodie, often surrounded by cola and snacks. It became a viral sensation as it perfectly encapsulates goblin mode—the relatable feeling of immediately dropping all social pretenses to indulge in laziness, video games, and junk food the moment one gets home. It is widely used to represent secret habits, the relief of solitude, or the stark contrast between one's professional persona and true chaotic self.
