The line comes from Rick and Morty Season 3, where Rick Sanchez interacts with Noob Noob, the unassuming janitor for the superhero team the Vindicators. Rick, who usually dismisses everyone around him, singles Noob Noob out for praise, which makes the approval feel both unexpected and funny. Clipped from that scene, the two-second exchange spread on soundboards and in meme edits as a quick way to endorse someone who finally understands something. Its appeal endures because Rick's rare, deadpan compliment works as instant validation in almost any context.
