The cry comes from Angry Birds, the mobile game series created by Rovio, where Chuck is the fast yellow bird known for speeding through the air. In the games, short hurt sounds like this play when a bird takes damage or crashes, giving each character a distinct comic voice. Clips of those reactions were later shared on soundboards and in meme edits, where the brief 'Auh!' became a handy shorthand for a sudden bump. Its appeal has lasted because it is instantly recognisable to players and needs no context to land as a joke.
