Angry Birds Star Wars was released by Rovio in 2012 as a crossover between Angry Birds and Star Wars, with birds cast as heroes from the films. Chewbacca becomes Chewie, a big furry bird whose ability is a roar, and this short growl is his in game sound. Clips of gameplay spread on YouTube and soundboards, and the bite sized roar survived beyond the game as a meme effect because it captures Chewbacca in less than a second and works anywhere a comic growl is needed.
