That's not English, that's some kind of new English-based language used mostly by teenagers.
Yes, Not itself an English word. Perhaps mostly used in the chatrooms.I'm seeing this being used often in another forum I frequent(native speakers and not a teenager forum) and when I looked it up in the dictionary I found out that it's somehow the abbrevation for that word.

How in the world will such dictionary know what you want to say?
I did not mean for a dictionary to know what I want to say, what I meant was that maybe there would be a dictionary which has seprated the similar words or some words related to a certain meaning or a certain TOPIC so it makes it easier for you to perhaps find the word you want.
