Oh for goodness sake, you can't try to get people to agree to adopt a meme and expect it to get any traction.. It's something that has to happen on it's own. That's what a meme is: an idea or concept that passes from one person to another through imitation.
You can use it yourself in your own vernacular by all means and if people start to copy it on there own, then it's a meme. If you try an *tell* people to imitate you, I can pretty much guarantee most won't and will ridicule the few that do and it will die a pretty quick death. Indeed, true memes last for generations, if not centuries and millennia. Most of this crap on the internet that are called memes won't last anywhere near that long, probably not even a decade before they fall into utter obscurity and so it's mostly just a series of fads. Seriously, try the "arrow to the knee" gag on someone in five or ten years time and all you'll get is a blank stare. Hell, try it right now and you're likely to get a flick round the ear hole.
