The phrase estas hablando is everyday Spanish, but as a short isolated clip it has circulated online as a standalone reaction sound rather than a full song or scene. Shared on soundboards and in chat groups, it is used out of context on purpose, so listeners do not need to speak Spanish to understand the scolding tone. Its brevity and abruptness helped it fit the meme format of short voice notes, remixes and video captions where a single line is repeated to mock someone talking too much.
