hacked off

adj. [analogous to pissed off ] Said of system administrators who have
become annoyed, upset, or touchy owing to suspicions that their sites have
been or are going to be victimized by crackers, or used for inappropriate,
technically illegal, or even overtly criminal activities. For example,
having unreadable files in your home directory called worm , lockpick , or
goroot would probably be an effective (as well as impressively obvious and
stupid) way to get your sysadmin hacked off at you. It has been pointed out
that there is precedent for this usage in U.S. Navy slang, in which officers
under discipline are sometimes said to be in hack and one may speak of
hacking off the C.O..
