The Angry German Kid videos began in Germany in the mid-2000s, featuring the fictional teenager Leopold Slikk losing his temper while playing a computer game. Clips of his shouting, keyboard smashing and tantrums spread through YouTube, forums and remix culture, inspiring countless parodies, dubs and edited versions. The scream became one of the most recognisable sounds from that era, shorthand for uncontrolled gamer rage. Years later it still appears in memes and reaction edits because the performance is so exaggerated and instantly recognisable, even for viewers who never saw the original videos.
