The sound comes from a 2021 video in which wrestler and actor John Cena, promoting Fast and Furious 9 in China, spoke Mandarin to his Chinese fans and mentioned eating ice cream. Clips of his enthusiastic delivery spread on TikTok, YouTube and other platforms, where fans remixed the phrase bing qi lin into edits, songs and reaction videos. Its charm lies in Cena's earnest effort to speak the language, and it remains popular as a lighthearted shorthand for enjoying food, travelling or embracing a meme moment.
