This clip is commonly shared online under Korean labels such as 엔딩송 and 엔딩브금, which simply point to it being used as ending background music. The exact original source is not clear from the available metadata, so it is best understood through its meme usage: creators use it as a compact outro cue on short videos, edits and reaction posts. Its staying power comes from how quickly it signals “the scene is over,” similar to other instantly recognizable TV-style stings like the Law and Order DUN DUN.
