AF
Heart rhythm disorder
AF is internet slang for "as fuck," an intensifier: This test is hard AF.
In military contexts, AF abbreviates Air Force: He served in the AF for twenty years.
The all-caps form appears in both casual digital communication and official military references. (Lowercase af is the same slang usage.)
