What kind of social network or game can I find these people?

I've been searching for some friends that I can hang out with online when I'm not busy with working on projects or homework. Something that screams kawaii and friendliness. Something for people usually 12+ where the people seem to have emotion. Let me give you an example of what I don't want:
Me: "Hey!"
Person: "hi"
"What's up? "
"nmu"
Me: "Uh… Yeah."
Person: "ya"

This is something I DREAD. I'm 16 and friendly with a good personality; adventurous and I need interesting facts and experiences without the hassle of getting a car and using gas money to pick people up, take them out and just talk. Like ew. I could go out and meet people but this is for when I don't feel like doing anything on the weekend and just chatting and meeting lots of new people that are at least somewhat intelligent and have emotion. I've tried Roblox and wow… It's just a bunch of swagfags, brainwashed fools, and idiots, plus some little children. I need something like a social networking or game that deals with meeting people and just having fun. Not so much adults tho… If you catch my drift o~o. Heh, but yeah, if there's any game thats like Roblox or Facebook but more for teens and maybe up to 21ish with some Anime hinted in there if possible; that would be great.

Not:
Roblox
Facebook
Myspace
Minecraft
Omegle
Runescape

There's no social site where everyone talks exactly the way you want. ROBLOX is a great game beyond social however, you make your own game within it literally and share it with the world! A great place to start is "ROBLOX Building Guide" on Amazon!

You can find good ROBLOX users in the Building and Scripting forums, generally in-game you won't see a lot of "good users to chat with".
