hacked off
hacked off: [analogous to `pissed off'] adj. 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.
