The sound comes from the Nippelboard of TV total, the German late night show hosted by Stefan Raab that ran on ProSieben from 1999 to 2015. Pressing a button on the board replayed short, out of context quotes from German television, and this angry Drecksschwein line became one of its reusable insults. Clips from the board spread widely online and in German chat culture, where the phrase survived the show itself. It is still dropped today as a nostalgic, exaggerated way to call out messy or shameless behaviour without starting a real argument.
