Holmescest is the incredibly wrong and creepy ship from the BBC television series Sherlock. It includes Sherlock Holmes and his brother Mycroft Holmes. It's mainly slash written by board people, and also has the ship name "Mylock" or "The Consulting Government". It was probably invented to scare Johnlockers and Mystraders.

Johnlocker: ...
Other person: *cackles*
