Fawnlock

Certainly it would be hard to guess why individuals dressed as humanoid woodland animals would be at a Holmes convention if you weren’t familiar with Fawnlock stories and art, in an Alternate Universe where Sherlock is a deer-like creature with antlers and fur.

One of my oldest informants, adagio, confirms this in an e-mail interview and admits to sometimes feeling as if fandom is deviating too far from the story told on the show: "I don‘t really see the point when the names is all that‘s left. I don‘t get things like fawnlock or tunalock at all, but I guess it‘s amusing. … Sometimes I think the internet has made it too easy to publish stories."

Sometimes the thematically focused groups are a clear subset of shippers, such as teenlock, femlock, vamplock, or fawnlock (respectively describing John Watson/Sherlock Holmes as teens, women, vampires, or young deer).
