1. (common) Stands for "as fuck".
2. (photographic) Short for autofocus. Sometimes combined with other letters, e.g. when talking about camera-side, AF-S is single autofocus (only done the moment you tell it to) and AF-C is continuous autofocus (done constantly between turning it on and off).
1. Dude, calm down, you got no chill and are angry AF!
2. What are you doing, shooting wildlife shots without an AF lens? Unless the animals are tranquilized, but then there's nothing interesting in that.

American Field Service (AFS) is the best worldwide exchange organization. Students can travel all over the world, meet people from other countries and learn new cultures. After their foreign exchange year they still can voluntary work at AFS. The organization is also known for their energizers.
People from AFS are always crazy, awesome, friendly, openminded, wonderful,... people.

AFS is one big family.
