Does this count as a game or a meme?

I've been dabbling in various fandoms and lurking in more for well over a decade now, and I've learned a thing or fifteen about how fandom trends distort canon. So . . . pick a fandom that's big enough on LJ, DW, and Tumblr for even people who don't know the canon to be aware of it. I'll tell you what I would think the canon was about, based on the fandom, if this were my first time at the rodeo.
