adj. Disgusting in design or function; esthetically unappealing. This word is seldom used of people.
"This keyboard is bletcherous!"
(Perhaps the keys don't work very well, or are misplaced.) See losing, cretinous, bagbiter, bogus, and random. The term bletcherous applies to the esthetics of the thing so described; similarly for cretinous. By contrast, something that is 'losing' or 'bagbiting' may be failing to meet objective criteria.
