A fuckin terrifying fandom. If anyone mentions it, run. Superwholock is the fandom of three television series: Supernatural, Doctor Who, and Sherlock. It’s like 85% of Tumblr’s content.
Person 1: “Ah so Ive officially joined the superwholock fandom!”
Person 2: *runs to another continent*
Get the Superwholock mug.
