The sound is listed simply as the Chinese character for leg, with the slug tui taken from its pronunciation in Mandarin. No source work, speaker or original recording is identified in the listing, so its history is really an online one. Short single word clips like this circulate on soundboards because they are easy to preview, share and drop into edits without context. Its appeal comes from that lack of context, and it continues to be used as a brief, random interjection in memes, chats and short videos.
