FOAD

Short for Fuck Off And Die, used quite often in the direction of a luser when he/she screws up months of hard sysadmin work.

An example (from Abigail, posted on alt.sysadmin.recovery): "Some luser was given root so he could install some things on a Solaris machine. Luser sees that / only has 60Mb free space. Luser sees that /var doesn't have it's own partition, but there's a partition /local. Luser thinks "must fix!". Luser issues "mv /usr /local". Luser is disappointed I tell him to FOAD and that he should try to salvage with what's available in /sbin, and if not, I've a CD for him he can use to reinstall the OS.

I learned this expression (which stands for "Fuck Off And Die") through the occasionally sullen Larry Mullen, Jr., U2's drummer. It is his favorite saying, according to the book U2 At The End Of The World, by Bill Flanagan.

During a staged protest of the Sellafield Nuclear Power Plant in England, U2 were playing with the Semaphore flags, like the ones the Beatles used on the cover of their 'Help' album. The idea was to videotape them moving from HELP to FOAD. Unfortunately, by that time, sleep deprivation and radiation suits that made them look like clones of the Michelin Man had taken their toll and the event turned into a swordfight with the flags between the members.
