This clip comes from JonTron, the comedy YouTube persona of Jon Jafari, whose exaggerated vocal reactions became widely reused in meme edits and reaction compilations during the 2010s. Sounds like this spread beyond their original videos because creators could drop them onto almost any visual gag and instantly signal shock, discomfort, or disbelief. The drawn-out delivery makes it especially reusable in short-form edits, where a single recognizable reaction sound can carry the joke even without showing the original JonTron footage.
