The phrase comes from everyday Indonesian slang, where serem means scary or intimidating and jabatan refers to a person's official position. Online, the clip spread as a reusable reaction on meme pages and short video edits rather than as a line tied to one confirmed source. Creators use it whenever a title like manager, chairman, or senior official is revealed, letting the voice do the exaggerating for them. Its appeal is how specific the wording feels while still fitting many workplace, school, and gaming situations where rank suddenly matters.
