These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: Some Metaguards were bemused, or convinced that an imposter was speaking, when the normally calm and calculating Sicon began to geek out about awesome swords in the chatroom.
And then Mr. A Appreciation Day temporarily split the tropers with some finding it fun and some finding it annoying.
Crack Pairing: The Cheshire Cat tried to troll Mr. A by pretending to ship the two of them with each other.
Crazy Awesome: Fiction bleeding into reality would probably invoke this trope on its own. An entire forum dedicated to said premise and populated by tropers, though, is pretty much a breeding ground for it.
In terms of characters, The Wicked Witch and Don Quixote are candidates. The former summoned a dinosaur through a wormhole and ate it, and the latter stole a police horse and named it Rainbow Dashnote and later Binky.
Mr. Administrator / Wicked Witch: came to be after the latter's Villainous BSOD, when her nature as Tsundere was brought up again.
Mr. Administrator / Cinderella: after Cinderella's disappearance, this particular shipping surfaced from a theory that she was sent into the Void Between the Worlds, and Mr. Administrator didn't mention it because he was embarrassed.
Mr. Administrator / EliGoneCrazy: He continually flirts with her on twitter, to the point that her fellow Metaguards decided that Mr. A has a crush on her. Her profile picture indicates that it may be mutual. This ship is known as Eliministrator.
"I'm dead serious. And after all we've been through,I should marry her. She rejected me, but I won't give up."
Jeroic tweeted at Mr. A shipping him and Morgan, even before Moriarty was refictionalized.
Mr. A: EW.
That One Puzzle: The Pheeble Locator puzzle had tropers confused for ages since it first popped up because it was difficult to pin point the coordinates in the compasses that the page gave to each troper who visited it. The website was eventually edited to add distance values for each compass in the coordinates, allowing the puzzle to be finally solved. The coordiantes pointed to locations of Peter Pan statues around the world which were an echo.
