The phrase comes from a May 2021 promotional video in which John Cena spoke Mandarin while holding an ice cream to promote Fast and Furious 9 in China. His pronunciation of bingqilin, meaning ice cream, was heard by English speakers as bing chilling and spread widely on TikTok. Remixes later paired the clip with Among Us slang, where calling someone sus implies they look guilty, and with jokes about Chinese social credit scores, keeping the sound alive as shorthand for cheerful, suspicious behaviour.
