Awesome Music: The Metaguard collaboration of Making Metaguards Out of You (an homage to the song "Make a Man Out of You" from Mulan) in honour of Don Quixote. (Go on, TRY to stop listening to it.)
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.
Difficulty Spike: The players hit one once real world events became an important aspect of the game. It seemed like no matter what location the PM's picked, the players did not have easy access to it or the available equipment to complete the objective.
Ending Fatigue: Everyone started to run out of steam by December, with the ARG ending sometime around 21st.
Don Quixote has become much more popular than pretty much any other character, partially due to the above mentioned awesomeness.
Brad also became rather popular thanks to him helping out Quixote with stopping Deanna and accompanying him for the rest of the time in the hospital and world.
From a typo in the chatroom: BONSUS (instead of bonus. It's more... bonsus than plain old bonus). Later, it came to mean notable typos, and got itself an Opposite-Sex Clone called Bobsus.
A typo in the chatroom (TRAM instead of TEAM) evolved into the Metaguard Tram, also known as Team Tram. WE ARE ON A TRAM.
A misinterpretation of "w/e" made some say "with elephants" instead of "Whatever".
#BlameEli and #AdellWasRight have taken on lives of their own on the Metaguards' twitters.
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.
Several ships have been made between players, much to their embarrassment/annoyance.
After the video of their fight, some Metaguards became convinced of Edward x Joe.
In-game, it looks like the hospital staff were shipping Quixote x Brad. Quixote calling Brad "my hero" repeatedly probably had something to do with it.
"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.
Viewer Gender Confusion: Happened so often and with such a wide range of metaguards that it was soon added as one of the rules of the Forum's Drinking Game.
