Coming from the universe of Battletech and MechWarrior, "Aff" is an abbreviation of "Affirmative," meaning "yes." Its opposite, naturally, is "Neg," short for negative.

When expecting an answer one way or another, the prefix "qui" may be added.

Gunter: "Enemy Kodiak at 2 o'clock. Should I open fire, quiaff?"
Von Helsing: "Aff. Take out his legs."

aff

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.
