The line comes from The Stanley Parable, a first-person game famous for its witty narrator who comments on every choice the player makes. Because the narration is usually calm and polite, a sudden blunt judgement like this stands out and is easy to lift out of context. It has since circulated on soundboards and in short meme edits, where creators use the narrator's detached tone to deliver an insult without raising their voice. That contrast keeps it useful as a quick, understated reaction.
