In the increasingly popular fandom for BBC's Sherlock television series, Jimlock is the 'ship name' of the pairing of Sherlock Holmes and his nemesis James (Jim) Moriarty.
This pairing is particularly popular because of the rivalry between the two (in the fangirl mentality, apparently male rivalry=gay relationship), and because of the similar degrees of intelligence that the two men possess.
Jedlock - when someone called Jed catches you in an unexpectedly long conversation about nothing interesting and that you cannot escape. Similar to a headlock but using annoying language. You are too polite to tell them to bog-off.
Related term: "Holy Jedlock" (when you're sadly married to the git due to poor judgement or severe misfortune).
"I was just caught in a Jedlock for 10 minutes by the toilet. It was a nightmare.". "Shh. I'm just hiding here to avoid a Jedlock.. Has he gone, yet?". "Ha ha! He had you in a nasty Jedlock there! Still, at least you know a lot more about squirrels now".
Braided sideburns that are twisted and ugly like the people that invented them. Or a Decorative ornamant you hang on your front door in the shape of a swastica or Hitler figure that wards off those dirty unwanted ones...
