With no clear credited source, this clip spread as a generic soundboard and meme reaction rather than a quote tied to a known show or creator. Short vocal callouts like this travel easily between edits because they need no context, and the word weeaboo already carries a long history as slang mocking non-Japanese fans obsessed with Japanese pop culture. Uploaded to soundboards and reused in gaming, anime and chat clips, it survives as a quick shorthand for spotting exaggerated otaku behavior in a scene.
