This short reaction phrase spread through soundboards and short video edits as a reusable reply to tangents and non sequiturs. Because no specific scene or character defines it, creators treat the line itself as the joke, dropping it whenever a conversation drifts off topic. Its plain wording makes it easy to understand out of context and simple to pair with reaction faces, chat screenshots and awkward pauses. It remains popular for the same reason people say it in real life, as a quick way to question relevance without a long explanation.
