AFK

But dont worry. I learned it the hard way too.

When I first heard the term AFK I was playing on a game server, and it kept saying "<username> is now AFK". For some reason I thought AFK was a rank, and I kept asking random people what I had to do to attain the AFK rank. It's hilarious looking back.
