abuse, operating system
/skuhm'os/ or /skuhm'O-S/ An Unflattering hackerism for SunOS, the Unix variant once supported on Sun Microsystems's Unix workstations.
Despite what this term might suggest, Sun was founded by hackers and still enjoys excellent relations with hackerdom; usage is more often in exasperation than outright loathing.
