The 'San Francisco Karen' meme stems from a June 2020 viral video involving Lisa Alexander and Robert Larkins, who confronted a man named James Juanillo for stenciling 'Black Lives Matter' on his own property in San Francisco. The couple claimed he was breaking the law and stated they knew the homeowner, only to be proven wrong when Juanillo revealed it was his house. The image became a symbol of racial profiling and the 'Karen' phenomenon—where individuals exert perceived authority or call the police over non-criminal activities. It is widely used to mock intrusive neighbors, false sense of superiority, and moments where someone is caught being confidently wrong about someone else's business.
