The exact original source of Oh My Kami is not clearly documented, and the clip circulates online mainly as a standalone reaction sound rather than as a named scene. That ambiguity has not stopped creators from adopting it, because the phrase is short, instantly readable, and easy to place over visual surprises. It appears most often in meme edits, short-form videos, and reaction compilations, where a single surprised line can carry the whole joke. Its continued use comes from that flexibility, working across fandoms without needing the viewer to know a specific show.
