[from Australian slang] Yet another
approximate synonym for broken. Specifically connotes a
malfunction that produces behavior seen as crazy, humorous, or
amusingly perverse. "That was the day the printer's font logic
went wonky and everybody's listings came out in Tengwar." Also in
`wonked out'. See funky, demented, bozotic
casters-up mode n.
[IBM, prob. fr. slang belly up] Yet
another synonym for `broken' or `down'. Usually connotes a
major failure. A system (hardware or software) which is `down'
may be already being restarted before the failure is noticed,
whereas one which is `casters up' is usually a good excuse to
take the rest of the day off (as long as you're not responsible for
fixing it)....
