The name comes from Köfteci Yusuf, a well-known Turkish chain serving köfte, but the exact original video behind this 31 version is not widely documented, so the clip is best understood as a TikTok-era meme sound. It spread through short edits and reaction videos that reuse the name as a punchline, often without needing the original context. Its appeal is the mix of a familiar everyday brand name with the randomness of TikTok humour, which keeps it useful for creators who want a quick, recognisable joke that lands instantly with Turkish-speaking audiences.
