Internet slang for a devoted fan of British actor Benedict Cumberbatch, known for roles in Sherlock, Doctor Strange, and The Imitation Game. Cumberfans are notorious for their intensity — think obsessive social media presence, fan fiction, and fierce defense of their favorite actor. The fandom gained particular momentum in the early 2010s with Sherlock's BBC run and spawned a whole ecosystem of fan art, memes, and shipping culture. Sometimes used self-deprecatingly by fans themselves.

As a proud Cumberfan, she had every episode of Sherlock memorized and a signed poster above her desk.
Origin: Portmanteau of "Cumberbatch" and "fan," coined organically by the online fandom community around 2010–2012 during the peak of BBC Sherlock's popularity. Editorial expansion authored on Slangora.
