Meghan Daum wrote an interesting article about the current use of the word meme , which was coined by Richard Dawkins for the way evolutionary principles can be used to explain how cultural ideas take hold. That sure has changed, as Meghan indicates!
Suddenly meme seems to be equated with stereotypes, in some cases rather negative ones. While I know that language evolves, that certainly wasn't how it was conceived of by Dawkins. Here is the definition from the World English Dictionary: "an idea or element of social behaviour passed on through generations in a culture, esp by imitation."
[As an aside, interestingly, the article I linked to in the Sacramento Bee did not mention Chicago in the above quote; the one in the Chicago Tribune added Chicago to the list of city memes; it said "Chicagoans deal with snow."]
I thought that meme was the term used to describe those internet quizzes and things that "everyone" is doing. Now I've found, also, that meme is a term that covers any actual internet phenomenon. This definition you are giving us is even more interesting and "out there" to me! I'm amazed!

Here's an interesting take on being " memed ."
