This clip was uploaded to the soundboard by the user leks2015 under the title Super Boos, and its exact origin is undocumented, so it is best treated as a generic spooky vocal rather than a quote from a specific game or show. At just over two seconds long it behaves like a classic soundboard button: short, repeatable and easy to drop anywhere. It has picked up a small handful of plays from people looking for a quick boo-style scare, and it survives on that simple usefulness, a tiny burst of cartoonish fright for prank and reaction edits.
