Deltarune is Toby Fox's role-playing game connected to Undertale, and its Holiday family has become a favourite focus for fan edits. Noelle Holiday is one of its central characters, while her older sister Dess is a mysterious figure frequently discussed by the community. This December chant circulates among fans as a seasonal in-joke tied to that family name, appearing in soundboards, holiday edits and short videos each December. Its staying power comes less from a single scene than from how easily the repeated word fits festive Deltarune content.
