Dory was introduced in Pixar's Finding Nemo in 2003, voiced by Ellen DeGeneres, and returned as the lead in Finding Dory in 2016. Her cheerful, forgetful personality made her short exclamations easy to clip and reuse outside the films. As soundboards and short-form video grew, brief character cheers like this whoop were shared as standalone reactions for good news and comic relief. It remains popular because the emotion is instantly readable without context, and the voice is closely tied to a widely loved family film character.
