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 MUDs
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.
