Labubu is the wide eyed, toothy character from The Monsters series by artist Kasing Lung, popularised globally through Pop Mart blind box toys. The character exploded on TikTok and social media as fans filmed unboxings, outfits and collections, and short chant sounds like this labuubu loop became a signature audio for those posts. Creators reuse it to instantly mark a video as part of the Labubu trend without needing any explanation, which is why it keeps spreading beyond collectors into general meme edits.
