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.
About this sound
A repeated December chant from Deltarune, linked to Noelle Holiday and Dess, that fans drop into holiday memes, seasonal edits, and fan tribute videos.
The clip is a short, high-energy vocal moment built almost entirely around the word December, shouted over and over until it turns from a name into a chant. Each repetition lands a little more urgently than the last, giving the audio a playful, almost manic holiday energy that is easy to recognise even out of context. Listeners familiar with Deltarune tend to hear it as a teasing, festive in-joke rather than a serious line, and that contrast is what makes it land so well in short videos. It works as a sudden burst of seasonal excitement, a punchline, or a way to mark a December-themed moment.
