The 67 trend grew into a viral short-form joke in 2025, repeated as a chant, caption, and reaction sound across TikTok and meme pages. This version adds a Catalan twist, pairing the number with bon Nadal, the Catalan way of saying a merry Christmas, so it fits seasonal posts as well as ordinary meme edits. Because it is only a few seconds long and instantly recognisable, creators keep reusing it for holiday greetings, December reaction clips, and lighthearted year-end videos.
