The phrase comes from a 2021 video in which wrestler and actor John Cena speaks Mandarin while talking about ice cream, pronouncing bingqilin, the Chinese word for ice cream, as bing chilling. The clip was picked up by TikTok users, who turned the cheerful mispronunciation into a running joke and a reaction sound for food, travel and language videos. Its appeal has lasted because the moment is good-natured, instantly recognisable and easy to reuse, even for viewers who know Cena only as a meme figure rather than a wrestler.
