Angry Birds began as a mobile puzzle game from Finnish developer Rovio in 2009, built around birds launched from a slingshot to defeat pigs. Its squawking, yelling birds became instantly recognisable as the game spread to phones, merchandise and animated spin-offs, and clips of their cries were soon reused in online videos. This scream works because it carries that familiar cartoon anger in under two seconds, making it a quick shorthand for frustration or reckless charging in memes, gaming edits and reaction videos today.
