From the series of Sherlock BBC. Originally Sherlocked, which means to be obsessed/in love with Sherlock. Johnlock means you ship Johnlock (John and Sherlock) very hard.
Friend: OMG I just finished watching Sherlock and i love it!
Friend 2: Do you ship Johnlock?
Friend: Bitch, please I am Johnlocked!
Person 1: Hey, what happened to Josue? I heard he got his neck snapped last night Person 2: Yeah, he accused Yohan of johnfoolery and paid for his behavior
Person 1: Ah I see, NO ONE dares mention John Travolta around Yohan
Very similar to a tomfooler, one who commits johnfoolery. Even more foolin' than a tomfooler. Term given to those who venture into the dark, mysterious realm of tomfoolery and return a new person, not the tomfooler they left as, but as the more evolved and ever-fooling johnfooler
No longer a tomfooler, Jacob emerged from the debacle a new man, a johnfooler if you will.
The OT3 made up of John Watson, Sherlock Holmes, and Mary Morstan. The ship is quickly gaining popularity, and will probably soon rival Johnlock as one of the most shipped ships in the fandom.
Sherlockian 1: Johnlock will always be my OTP, but I'm really beginning to see the appeal of Johnlockary.
Sherlockian 2: Eww! What "appeal" could there possibly be?
Sherlockian 1: CRIME-SOLVING MARY. JOHN GETTING BOTH. SHERLOCK HAVING TWO LOVERS. THREESOMES. *grabs Sherlockian 2's face and whispers* Threesomes.
