The clip circulates online under the Korean title 터미널jj, romanized here as Teomineoljj. A clearly documented original source is not widely established from the available information, which is common for niche meme sounds that spread through reposts and private shares. Its staying power comes from recognizability within small communities and from how easily it fits short-form edits, reaction videos and chat-group humor. Even when viewers do not know the origin, the sound still works because the name itself helps people refind and reuse it.
