Angry Birds began as a mobile game by Finnish studio Rovio Entertainment in 2009 and grew into one of the most downloaded game franchises ever, spawning sequels, cartoons and two animated films in 2016 and 2019. Cheering stingers like this one come from the series' victory moments, where the flock celebrates a cleared level, and they work much like a triumphant yay in meme edits. Clips of game audio spread through soundboards and short-form video, where creators grab a few seconds of celebration to punctuate wins, and this six-second cheer remains a go-to because it reads as happiness instantly.
