Coldmirror is the alias of Kathrin Fricke, one of Germany's earliest YouTube stars, known for the Harry Potter und ein Stein parody series that began in 2006. She also produces absurdist fake commercials, tagged by fans as Scheißwerbung, mocking advertising language and consumer culture. Konsum und materieller Wohlstand translates to consumption and material prosperity, a typical slogan she delivers with heavy irony. The line circulates on German meme soundboards as shorthand for satirizing greed, haul culture and overpolished brand speak.
