:FOD: /fod/ v. [Abbreviation for `Finger of Death', originally a
spell-name from fantasy gaming] To terminate with extreme prejudice
and with no regard for other people. From {MUD}s where the
wizard command `FOD <player>' results in the immediate and total
death of <player>, usually as punishment for obnoxious behavior.
This usage migrated to other circumstances, such as "I'm going to fod
the process that is burning all the cycles." Compare {gun}.

In aviation, FOD means Foreign Object Damage, e.g., what happens
when a jet engine sucks up a rock on the runway or a bird in
flight. Finger of Death is a distressingly apt description of
what this generally does to the engine.
