RWBY is a long-running American animated web series created by Rooster Teeth, following young hunters training to fight monsters in the world of Remnant. Short dialogue lines from the show have long circulated as reaction sounds on soundboards and in fan edits, because they are easy to lift from a scene and reuse over unrelated footage. This line fits that pattern perfectly, offering a concise way to mark a moment that has moved past surprising into strange. Its popularity endures because the sentiment applies far beyond its original scene.
