The Angry German Kid is one of the internet's oldest viral stars. The original video, surfacing in 2006, shows German teenager Leopold Slikk flying into a screaming rage while playing Unreal Tournament on his PC, smashing his keyboard as his laughter tips into mania. Dubbed the Keyboard Crasher, the clip exploded across early YouTube and inspired thousands of subtitled parodies plus the long-running AGK episode series. That unhinged cackle became shorthand for someone completely losing it, and meme editors still drop it into rage compilations and parody dubs today.
