1.
AFK
"Away From Keyboard"
This means that you are temporarily away from the keyboard during an online game with other humans.
In an online role-playing game you are chatting to your mates. Then you must leave the computer so you say:
"I'm AFK for a bit".

They then know that you are away for a bit.
