The exact origin of this clip is not documented, so it circulates mainly as a user-uploaded soundboard line rather than a quote tied to a specific show. It caught on because the phrase is instantly usable: anyone editing sibling-themed anime memes or protective big-sister and big-brother gags can drop it in without context, much like other anime meme sounds built around a single catchphrase. Its staying power comes from repetition across edits where a sibling character shuts down a rival, and it sits comfortably next to onii-chan clips in reaction-style compilations.
