No documented origin has been attached to this short phrase, and it circulates as a reusable sound rather than as a quotation from a film, show or viral video. Its file metadata points to a voice-changer tool, which fits the processed delivery heard in the clip, but the recording session behind it is not established. Online, short clips like this survive because they are easy to drop into edits, repeat in comments and reuse as an inside joke. The odd specificity of refusing butter gives it enough meaning to work without a larger story.
