ScumOS

n. Unflattering hackerism for SunOS, the UNIX variant supported on Sun Microsystems's UNIX workstations (see also sun-stools), and compare AIDX, terminak, Macintrash Nominal Semidestructor, Open DeathTrap, HP-SUX. 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.
