And by explanation, I mean "WHY."
First off, what the buck I was rambling on about when I started the post- Well, at that point, I was dead set on Aaron, and the 'bucks everything out the window' bit was because I was trying to hide my prior involvement in 4chan up until that point.
That is, until I realized that absolutely nobody has sporked a badfic from 4chan. And I could tell, because nobody mentioned greentext, the strange hybrid of script and prose that makes up 99.99% of 4chan fics.
And that gave me the idea of a former 4chan anon turning around and sporking greentext badfic the same way that many other agents turn out to have previously written badfic.
As for actual 4chan "greentext," when they are posted there is always at least one anon there in the thread always have two or three Anons there to give him concrit, such concrit almost never goes past writing style or SPaG. "You" (the usual main character) are always a Gary Stu (and yes, here Gary Stus are the majority, not the minority) that Drops Into Equestria, usually without explanation, almost always with an inexplicable immunity to magic, and as for how the canon around you turns out...
I'm just going to bring up the "Flutterrape" threads from 4chan's /mlp/ board to answer that. No, it's the exact opposite of what you're thinking. "You" (man, I can see the usually-underused You crash dummy getting overworked fast here) are the main Gary Stu (or, rarely, , and the whole premise is that everypony wants to have sex with you to the point of raping you. And since Fluttershy is the, oh, I don't know, shy one in canon, she's the one that ends up being the most used target!
Excuse me while I proceed to blatantly ignore everything I say about brain bleach two paragraphs down and smash my head into a wall.
Going back to discussing the character, the part with "f*****" will probably be cut out or replaced with generic insults, mainly because I had forgotten that actual cursing was a Bad Idea here in the board.
The part about requiring less bleeprin is because I genuinely feel that 4chan experience could negate the need for brain bleach, at least partially.
As for appearance, that's me. However, the suit and the green items are a reference to "green-man Anon", a common stylization of Anonymous (or as he's referred in most 4chan greentext, "you") as a character, the idea being that the green skin, blank face, and bald head of the Green-Man Anon would work as a green screen, allowing pretty much anyone to be projected there.
