brain-damaged adj.
1. [common; generalization of `Honeywell Brain Damage' (HBD),
a theoretical disease invented to explain certain utter
cretinisms in Honeywell Multics]
adj. Obviously wrong; cretinous;
demented. There is an implication
that the person responsible must have suffered brain damage,
because he should have known better. Calling something
brain-damaged is really bad; it also implies it is unusable, and
that its failure to work is due to poor design rather than some
accident. "Only six monocase characters per file name? Now
that's brain-damaged!" 2. [esp. in the Mac world] May
refer to free demonstration software that has been deliberately
crippled in some way so as not to compete with the product it is
intended to sell. Syn. crippleware.
