FOD
/fod/ [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 " results in the
immediate and total death of , usually as punishment
for obnoxious behaviour. 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.
