The sound comes from a short Russian-language joke song built around the line 'Trenbolon kolyu v ochko,' slang for injecting the anabolic steroid trenbolone. It took off on TikTok, where gym and fitness meme pages turned the chant into a punchline for bodybuilder edits, workout fails and steroid jokes. Because the exact original upload is undocumented, it spread the way most TikTok audio does: copied from video to video until the phrase alone was the joke. Today it sits alongside other viral TikTok meme songs like chipi chipi chapa chapa and tung tung sahur as a go-to ironic gym anthem.
