SCSI | = S = | search-and-destroy mode

ScumOS /skuhm'os/ or /skuhm'O-S/ n.

Unflattering hackerism for SunOS, the BSD Unix variant supported on Sun Microsystems's Unix workstations (see also sun-stools), and compare AIDX, Macintrash, Nominal Semidestructor, 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.
