The 'Angry German Kid' (also known as 'Keyboard Crasher') features a teenager named Norman Kochanowski portraying a character named Leopold Slikk, who descends into a violent, screaming rage while trying to play Unreal Tournament. First appearing on the internet around 2005, the video became a foundational viral sensation on YouTube, epitomizing the 'gamer rage' trope. Although Kochanowski later revealed the video was intended as a parody of gamer stereotypes, it remains one of the most recognizable memes in history. It is frequently used to represent extreme frustration, tech-induced meltdowns, or the sheer intensity of online competitive gaming.
