Sidetalk launched in 2019 as a fast-paced Instagram and TikTok street show hosted around New York City, asking strangers rapid questions. Its 'bing bong' intro became a viral meme sound during the 2021 Knicks playoff run when fans chanted it outside Madison Square Garden. Clips spread across TikTok, sports broadcasts and edits, turning two simple words into shorthand for New York energy, trash talk and celebration that creators still drop before highlights and interviews today.
