Bing Bong became a viral catchphrase in autumn 2021 after Sidetalk NYC posted street interviews from Coney Island in New York, where interviewees shouted the phrase with infectious enthusiasm. Clips of the moment were reposted across TikTok and Instagram, turned into edits, remixes and reaction sounds, and soon used far beyond the original videos. It stuck because the phrase is short, easy to shout and instantly signals New York street culture, making it a handy shorthand for excitement, chaos and local pride in short-form video.
