Pa' que sepa is a common Spanish expression, especially in Puerto Rican and Caribbean Spanish, that translates roughly as just so you know and is often used to underline a point or warn someone. The clip circulates online tagged with Darell, the Puerto Rican reggaeton artist, and has been picked up as a short reaction sound rather than as a full song excerpt. Its brevity suits short-form video and meme edits, where a single assertive phrase can close a scene, and that reuse has kept it circulating long after its first uploads as a soundboard clip.
