Anything superfluous or annoying •Examples like the one following, though differing in the number of pounds, were ordinarily given as an explanation of the word, and the explanation was the fun: Gerber's confession was what Keisman called a ''blivit,'' four pounds of shit in a two-pound bag (WWII armed forces)
/bliv'*t/ [allegedly from a World War II military term meaning "ten pounds of manure in a five-pound bag"] 1. An intractable problem.
2. A crucial piece of hardware that can't be fixed or replaced if it breaks.
3. A tool that has been hacked over by so many incompetent programmers that it has become an unmaintainable tissue of hacks.
4. An out-of-control but unkillable development effort.
5. An embarrassing bug that pops up during a customer demo.
6. In the subjargon of computer security specialists, a denial-of-service attack performed by hogging limited resources that have no access controls (for example, shared spool space on a multi-user system).
This term has other meanings in other technical cultures; among experimental physicists and hardware engineers of various kinds it seems to mean any random object of unknown purpose (similar to hackish use of frob). It has also been used to describe an amusing trick-the-eye drawing resembling a three-pronged fork that appears to depict a three-dimensional object until one realises that the parts fit together in an impossible way.
