Some german kid mocking the boomer's idea that "video games make kids violent and affect their mental health".
He posted a video in which he was trying to boot up the computer to play unreal tournament, but the game was taking too long to start which caused the boy to lose his temper and start beating up his keyboard and yelling at the monitor, the video ended with him rage quitting after he lost the game, the boy yelled at the top of his lungs, took the keyboard and smashed it repeatedly causing it to break, all of this was just act to mock the boomer's perception of how their kids behave when
playing video games, but
unfortunately people who watched this video did not get the satire and mistook him for a kid who is
mentally challenged, which nearly ruined his life.
This video became a popular meme around the mid to late 2000s internet, a lot of people made parodies of this and even fan-fictional animations.
