Dafuqristmas comes from the WhatsApp audio meme culture where short voice notes are saved, renamed with joke titles and shared as reactions. The name is a pun combining an internet slang expression of disbelief with Christmas, which signals exactly how it is used. Like many WhatsApp audios, it spread through group chats and soundboard collections rather than a single official release. Its appeal has lasted because the holiday season reliably produces awkward, funny moments that need a quick irreverent reaction, and a five-second clip fits perfectly into memes and chat replies.
