Darth Vader is the masked Sith Lord from George Lucas's Star Wars films, voiced in the original trilogy by James Earl Jones, and his clipped, formal replies have become quotable on their own. Short lines like this circulated first on movie soundboards and later in meme edits and group chats as a sarcastic way to agree. Fans often pair it with the longer Darth Vader NOOOOOOOOO reaction for the opposite emotion. Its continued use comes from the contrast between Vader's menacing reputation and a phrase that sounds politely submissive in almost any everyday situation.
