DNF
adj.— «There is—or was—a cache there called “Valley View Too” which hadn’t been found since last May, though with only one “Did Not Find” logged since then. (Curiously, the caching slang for a failed search, “DNF”, is the same as the runners’ slang for a failed race, where it indicates “Did Not Finish.”)» —“Community watch” by Parker Morse Flashes of Panic May 2, 2004.
