Why would you say “Cumberbitches”? Benedict has both male and female fans; of the female fansalot of them don’t even want to be known by suchaderogatory fan-name. If you are going to involve the fan names then at least don’t insult the people you are addressing. Either use “Cumberbatch fans” or the term Cumberbatch prefers which is “Cumbercollective”. FYI there are loads of different offshoots, like Cumberbabes, Cumberbuddies, Cumberladies and Cumbergents.
