What's with grown men and my little pony?
I don't want to derail this, so I'll direct you to the pony thread where that's been answered a few times:

Or you could just ask /b/. You're bound to find the pony thread with just a few refreshes of page 0.
E: vvv: Well, MLP:FiM really isn't a meme, so Know Your Meme's failure to explain it well is understandable. You can get to the heart of Numa Numa, Nyan Cat, or Boxxy with just a video clip of a few seconds, leaving plenty of time to talk about internet reactions, sub-memes, and whatnot. But with MLP:FiM, the main foundation of its popularity is the fact that it's 22 minutes of quality, character-driven show, and you can't get that across without at least laying out the pilot episode. The memes the brony community makes which bank on our collective knowledge of the show need that context to be understood.
