The sound comes from First Christmas (Merry Christmas) by Zomboy, the British electronic producer known for aggressive dubstep and bass music. The excerpt circulated online under the short name christmasbass, where soundboard users clipped the most intense section for quick playback. Its appeal comes from putting a familiar seasonal theme against modern bass production, a contrast that fits meme editing culture. It remains used during December edits and in year-round bass drop compilations, often as a short, recognizable burst rather than a full song play.
