= K =
kill file n.
[Usenet; very common] (alt. `KILL
file') Per-user file(s) used by some Usenet reading programs
(originally Larry Wall's rn(1)) to discard summarily
(without presenting for reading) articles matching some
particularly uninteresting (or unwanted) patterns of subject,
author, or other header lines. Thus to add a person (or subject)
to one's kill file is to arrange for that person to be ignored by
one's newsreader in future. By extension, it may be used for a
decision to ignore the person or subject in other media. See also
