"Idle" is someones status that shows up to their friends when they are online. Unlike AIM, you can't just say "I'm away from my keyboard", it will just automatically put you as Idle if you don't click on anything for a certain amount of time. Idle basically means that you are doing nothing. If your on Facebook and your Idle, you would get the little grey crescent moon next to your name, instead of the green dot.

It means that facebook chat line has been opened and is idle after 10 minutes.
it means they're idle (away etc.) like on msn when they have a clock its the same thing for facebook chat except its a moon, however you cant choose to be idle you only have the option to be online or offline and if your online and you havent done anything for a while on facebook chat it automatically puts you to idle seeing how your online but not doing anything, hope that answered your question!
