I don't speak Popularese

I don't. I really don't.
Don't worry if you don't know what it means - it's a word I got from a book, the word I'd been searching for to describe the six certain people from last year. I've been searching for a way to describe their odd aura and virtual language that I could not penetrate for a year. I mean, there sure hadn't been anyone like that first through fifth grade. I didn't understand it.
My inspiration came from the book Trading Faces, by Julia DeVillers and Jennifer Roy, in the "mix" series. It's a little like Candy Apple - a series of books but almost all by different authors. This word comes up in this scene:

Payton brightened. "They saved me seats, and they were totally complementing me all the time! And did I tell you I'm going shopping with them at the mall this weekend?"
"Wow," I said sarcastically. "In seven hours you made FFBs!"
"It's BFFs." Payton rolled her eyes.
"Oh darn, I'm not fluent in Popularese," I said. "I guess I'm too busy concentrating on  important things."

That was the source of my random word thought. For a year, I was working to find a word or two that could summarise how I felt around those six people: meek and unable to keep up a conversation. I couldn't say anything to them; not because of fear, because I couldn't. I had nothing to say to them, once I got used to their Popularese.
I could listen to them for a whole recess and not understand what they were talking about. I'd have nothing to contribute to their conversations - since I didn't understand what the heck they were talking about, the only things I could contribute were things like "I know, right?", "Wow..." and empty things like that, which is exactly the kind of meaningless talk I wanted to avoid. Those words are the cheap chat tools people use in chats. Cheap ways of replying to other people's conversation, not saying anything original or of your own - showing anyone that you Don't Care.

Well, I'm having plenty of experience with these people. I haven't worked up a solid dictionary definition yet, but here are some things that can clue you in - if you're not Popularese, that is.

1. The only way you can describe them (before you hear about my word) is "popular" even though there might not be enough people in your school for them to be popular among.
2. You can't seem to keep up a conversation with them.
3. They use cheap convo tools on chats or IM. (E.g. "lol" "ikr" "yeah" "idk", etc etc) Mostly they "lol" at everything. It's a pet peeve of mine.
4. You feel en garde around them - like you can't relax and be however you are with your true friends. If you tell them something they consider awkard, they would vocal fry: "O-o-o-o-o-kaaaaaay...." in Popularese. I will post an audio exerpt later. They might act all this-is-sooo-awkward and as though they don't know what to say.
5. Even though you ARE technically socially on the same level, you instinctively think that you are not, and that they are more liked than you; therefore, it would be awkward for you to approach them.
6. You somehow . . . can't . . . approach them. Like it would take scraping up some nerve to do so.

BONUS POINT (one that is a BIG clue): Try recording one of their conversations during recess with a group of people. Even better - try to remember specific words or phrases. Can you? In my experience with a certain six (from now on known as the C6) one time they spent a recess talking about Temple Run. Those who had touchies, anyway. I can't remember any exact thing anyone said! Even when the recess was over. I only knew that the gist of it was Temple Run and that they were comparing scores or something. But all in, they really didn't say anything at all. Anything that mattered. I kept asking myself: How could you fill up a whole recess conversation with that empty junk? I can't do that.

In fact, there's a volume I could speak about saying so much, and yet saying nothing. Nothing of essence. How is that done? Why do people do that?
Looks like I'll have to answer that myself.
