The exact origin of this phrase is unclear, which is common for short user-generated soundboard clips that travel faster than their source video. Online, it has circulated as a standalone meme sound, shared and reused in short edits because the slang spelling and confident delivery make it easy to quote. Its appeal is not tied to one show, film or celebrity, but to the absurd image it creates: a dog somehow connected to butter. That vagueness helps it stay flexible, so creators can drop it into unrelated dog, food and reaction content without needing the original context.
