Short for "affirmative" and use much like "yes" or "indeed". This primarily from the Battletech universe (and the Mech Warrior games) where Clanners use it. It's still used by fans, though use is dying out.

AFF - Away From Facebook.

When you are not AFK (away from keyword) but only AFF (away from facebook) so you can be doing other things online.

The times at which you are not on facebook (i.e. doing work, watching porn and playing COD).
1) "OMFG, It's 1am and im still on facebook. I have an essay to do for 9am. That's it, I'm AFF"

2) Bob: "F*ck my life, what am I even doing on facebook?"

Steve: "Get the f*ck off it then!"

Bod: "Ok :(, I'm AFF!"

3) *hmmmm I need to masturbate* "AFF!"

AFF is an abbreviation they use for 'Accelerated Free Fall' and refers to the 9 stages involved in learning to become a solo skydiver. Skydive Oz Australia runs AFF Courses weekly - it's believed the term originated from there. The AFF stages are most commonly found within the solo skydiving 'A' Licence course. The AFF course facilities are found at Moruya Airport near Batemans Bay NSW 2536 Australia. The abbreviation is used amongst skydivers as a noun - You just AFF'd that up. You're a level 6 AFFwit.
Hey, I just completed my AFF and it was epic!
Piss of you AFF head.
