The Sherlock Fandom is possibly --no, certainly-- the crackiest fandom ever to exist. They can take anything (be it a shirt, tea mugs, an umbrella, or the characters themselves) from the show or the show's set and make it into a huge joke.

The members of this fandom are extremely close, to the point where they can complete each others thoughts and know everything there is to know about each other. They are extremely loud, though in a very good way.
They also refer to the writer of the show, Mark Gatiss, as "Godtiss", as they view him as a God.

The Sherlock Fandom is reportedly the first fandom to "break the 4th wall", meaning the actors of the show know of the fandom (and the porn). Martin Freeman was the first to acknowledge it, after he held up a sign reading "Te Quiero Jan y Rosalia", directed towards the admins of a Martin Freeman Sexual Frustration blog. The actors now enjoy trolling the fandom and tricking them.
Sherlock Fan: Tell us about Rupert Graves
Average Person: Ugh. The Sherlock Fandom is so stupid.

Fan A: PRAISE GODTISS!
Fan B: ALL HAIL GODTISS!

Fan A: Have you seen The Great Game?
Fan B: Oh my god yes. THE PURPLE SHIRT OF SEX.

The Sherlock fandom is one of the holy trinities of the fandoms on tumbler; the fandom contains an assortment of high functioning sociopaths who because of their “issue” with episodes have been left in a bored mess. The fandom is one of the most clever fandoms you can come across.
