It seems now days Instant Messaging has become a language of its own and if your not 16 or younger you can't even read it. Well help is on the way, I know the few I listed below won't knock too much of a dent in understanding the IM language, but I hope it helps a little!

ADAD
Another day, another dollar

DQMOT
Don't quote me on this

BITD
Back in the day

GOL
Giggle out loud

WYGOWM
Will you go out with me?
