The Angry German Kid became an early internet phenomenon through a home video of a German teenager, known online as Leopold, losing his temper while playing a computer game. Shared widely on video platforms in the mid-2000s, the clip was remixed, subtitled and parodied countless times, turning his shouting and keyboard smashing into shorthand for gaming rage. Years later, creators still reach for the best part of the rant because its uncontrolled energy is instantly recognisable, even to viewers who have never seen the full original video.
