The exact origin of this short clip is not clearly documented, which is common for user-uploaded meme sounds that circulate through soundboards and short-form video apps. Its title gives the joke away: a firm denial of being Blossom, used as a quick reaction to mistaken identity. Because the line is short, clear and easy to understand without context, creators have kept reusing it in edits, comments and reaction videos where a character or creator is confused with someone else. Its humour comes from that simple, universal mix-up rather than a specific show or scene.
