The sound comes from Angry Birds, the mobile puzzle game released by Rovio in 2009, where players launch different birds from a slingshot at structures built by green pigs. Each bird has its own chirps and yells, and short clips of those launch noises were later ripped and shared on soundboards and in Spanish-language meme edits as sonido angry bird. As short-form video grew, the squawk became a standalone reaction sound for anger, failed throws and cartoon chaos, separate from actual gameplay footage.
