The title is German and translates roughly to Bryan freaks out, which is exactly how the clip is shared on soundboards. It comes from gameplay of Grand Theft Auto V, the open world game where chaotic missions, police chases and unexpected deaths often trigger player meltdowns. Short rage clips like this spread because they capture a universal gaming experience in a few seconds, and German shouting in particular became a popular reaction format online. It remains used for gaming fails, rage quits and exaggerated anger jokes.
