I was reminded of this by the YKYWTMFMAW thread.
Many of my friends watch FMA, but only about half of us have actually finished the series. Therefore, since we hang out in large groups, those of us who have finished it can't exactly order the others to leave if we want to discuss plot twists. And most of us hate getting spoilers.
To deal with this difficulty, we have invented an elaborate code for discussing the later episodes sans spoilers. Since it's usually invented in the presence of people who haven't finished, some of the terms are very convoluted and took several revisions before anyone realized what a particular person were talking about. We've sort of standardized a few of the the terms, and I thought y'all might be amused by them.
The Orange: Amestris and its surrounding countries; the world of alchemy.
The Apple: Our world; the Other Side of the Gate.
The Way From the Apple to the Orange: The Gate itself.
The Orange Seed: Edward Elric (sometimes referred to as the "little orange seed" for clarity)
The Bigger Orange Seed: Alphonse Elric (but we make sure not to use it too soon after "the little orange seed" because it would be too easy to figure it out from context.)
Orange Seeds (in general): People from the world of alchemy.
Apple Seeds: People from the Other Side.
Matching Orange and Apple Seeds: Alternate versions of a character, like Alphonse Elric and Alphonse Heidel....herfen...whatever. ^^;
The Person Who Pushes Doors With Children: Dante
The Confused Person Who Sits By Graves: Hohenheim (sometimes also called the "maker of the little orange seed")
The Person Whose Children Are Used To Push Doors: Rose
The Armless Wonder: Scar (We also sometimes call Ed the Limbless Wonder, but not as part of the code, since it's too easy to figure out. Because of this running joke, there's the added bonus that our friends often think we're talking about Ed when we're actually discussing Scar.)
Nice Doggy, Let's Play: Nina!Chimera
Inverted Wombat: Tucker!Chimera (also represented by the speaker hanging their head upside-down off the side of the bed or whereever they're sprawled and whispering in their creepiest voice, "Edowaaaado...")
The Woman of Ishvar: Lust
Shrieking Burned Boy: Wrath (also called the Boy Who Runs Away From Doors)
Alien Conspiracies: Scieszka
Blue Jell-O: Sloth
Cyclops: Roy Mustang
The Person With the ALIEN BABYYYYY!!: Izumi-sensei (Also "Bye-bye, Alien Baby!", accompanied by a gesture of holding something up and watching it float away.)
The Person Who Peels Apples for Orange Seeds: Trisha Elric
The Person Who Makes Pies for Grave Robbers: Winry Rockbell
The Person Who Peels Apples for Cyclops: Riza Hawkeye
The Terminator: Robo-Archer
The Person Who Curls Up Like A Cockroach, Eeeeerckblekblaaarrghfargle!: Greed (usually accompanied by a graphic impression of Greed's final moments)
"Alas, Poor Yorick, the door is jammed!": A reference to the Roy/Pride showdown. Also called simply "Alas, Poor Yorick", "The Event in the Wine Cellar", and "Look Daddy, I--urk!!" *clutch at throat*
Terminator vs. Cyclops: A reference to Roy's near-death.
Zeppelin: Also "the land of Zeppelins". Another reference to the Apple. We like to mix things up a little. The "Zeppelin incident" is of course Ed's first death.
"First the zeppelin, now this? My life sucks!!": A reference to Edward's second death at Envy's hands.
A small serving of shishkebab: Another reference to Ed's second death. ;_;
Phone Booth: A reference to Hughes' death.
No, Doggy, Don't Play With the Bad Man: A reference to Nina's death.
"Orange Seed versus the Nazis!!!": Everyone's fervent wish for the movie. Usually yelled to the accompaniment of cheers and laughter. The best part is that people keep trying to guess what the "Nazis" represent. If they only knew...
(anyone raising their hand into the air and staring at it wistfully): A reference to the ending. Often followed by, "Do you think it'll ever happen?", usually answered by a chorus of "It had better!" and sometimes by "The orange seeds need to all be back in the orange!" or "The orange seed needs a permanent supply of pie, dang it!" (There are many EdWin fans among us.)
And that's just a sampling.
