The clip comes from Invader Zim, the Nickelodeon animated series that premiered in 2001 and built a lasting cult following for its frantic, over-the-top delivery. Short shouted lines from the show have circulated for years on soundboards and in fan edits, because a single phrase can carry the whole joke without any setup. This accusation survived in that format as a reusable call-out, shared in chats, streams and meme videos whenever someone wants an exaggerated, cartoon-style way to reject a claim instantly rather than argue with it.
