When I found out about MLP, it was from a YTP called "My Little Porno: Friendship with Benefits"
I didn't know about the fandom, until three days after it came out, when a comment in the video said "What's a Brony?' And I had no idea of it, and someone replied to that comment to the KYM article about it, After reading it, I thought it was just a bunch of people who would get high or drunk, and watch it, because as far as I saw from the YTP, its really fucking colorful, and isn't being drunk or high makes your vision weird, so seeing the colors would make it even more trippy I guess. I don't know what is the effects when you are high or drunk, and I didn't really look more deep into it at that point.
When I got a new laptop, I was hyped because I could finally play TF2 for the first time, and I realized How big it actually is. when servers was dedicated to it. When playing it, I kinda was starting to hate it, because alot of people when they put their sprays up on the wall, its Rule 34 of it. And I had the impression, it was just some people who did see it in that view. But now looking back on it, it was either trolls, or people who tried to "stop" it, because this was the summer where it grow exponentially! But like a month or two later, I was talking to a few people on a server of the game, and they were just talking about it, and that's when I had to know, what is this about, not the just the show, the fandom itself.
So to even begin looking at the fandom, I had to know the show, So, On Halloween of 2011, I usually watch a horror movie, since I really don't watch them a whole lot, and its usually when I watch one. That year was 1978's Halloween, and Since I'm a fucking pansy, I usually have something to watch if I got freaked out to much, and had to stop it, and just watch something that isn't the thing that was freaking me out. The first episode of MLP, was the thing for it. Though I got by the movie just fine, I still had to see this. After seeing it, I made a schedule to watch more, At first, One episode a week. Then Two episodes per week, then an episode a night, then finally, "Lets get the first season over with." And the finale of the first season, was the point where I unconsciously succumbed to it. My brain was still fighting it, but I wasn't really resisting it at all.
Soon enough, I caught up with the season 2 when it was like 10 episodes in I think, and was able to watch the show, as it came out. I didn't have an idea on how to really dive in the fandom, so I decided, The image gallery of MLP on KYM, was the place I should go to. A̶n̶d̶ ̶t̶h̶a̶t̶'̶s̶ ̶h̶o̶w̶ ̶E̶q̶u̶e̶s̶t̶r̶i̶a̶ ̶w̶a̶s̶ ̶m̶a̶d̶e̶. And that's how I kinda became a fan, and how I kinda been in the fandom really.
Sorry for being TL;DR, but that's kinda how it went, I wasn't one of those who immediately started to get into it, as soon as they heard about it. There are more details about the whole ordeal, but Its already gone to long. So yea, that's how it is. Here's Fluttershy with a mustache.
