This is streamer CaseOh caught mid-reaction, blurting out what did you just say in a loud, incredulous voice.

It lasts only a couple of seconds but lands instantly, turning an ordinary comment into a dramatic callout. Viewers use it because the over-the-top disbelief feels both funny and relatable, making any awkward, rude or absurd line sound ten times more serious than it actually was in the moment.
