Okay, I'm not completely dense (though sometimes it seems that way, I know), and I think I get the general idea, but I'd like to be sure I'm on the right track.

As I've mentioned in a couple past entries I've been reading Fandom_Wank again and I've seen "hate meme" come up a couple times.

Now I now what a meme is, and assume a "hate meme" is much the same, only with (you know) hatred. But sometimes the logical conclusion isn't the correct one, so I was hoping to get an explanation from someone who knows for sure what a "hate meme" is.

No, I'm not planning to make one or even go play on one, I'd just like to know what the bleepin' hell people are talking about when they mention or talk about someone doing a "hate meme."
