from WordNet (r) 3.0 (2006)
GIGO

GIGO
 /gi:'goh/

   1. `Garbage In, Garbage Out' -- usually said in response to {luser}s
   who complain that a program didn't "do the right thing" when given
   imperfect input or otherwise mistreated in some way. Also commonly
   used to describe failures in human decision making due to faulty,
   incomplete, or imprecise data.

   2. Garbage In, Gospel Out: this more recent expansion is a sardonic
   comment on the tendency human beings have to put excessive trust in
   `computerized' data.

Garbage In, Garbage Out
GIGO

   <humour> (GIGO) /gi:'goh/ {Wilf Hey}'s maxim expressing the
   fact that computers, unlike humans, will unquestioningly
   process nonsensical input data and produce nonsensical output.
   Of course a properly written program will reject input data
   that is obviously erroneous but such checking is not always
   easy to specify and is tedious to write.

   GIGO is usually said in response to {lusers} who complain that
   a program didn't "do the right thing" when given imperfect
   input or otherwise mistreated in some way.  Also commonly used
   to describe failures in human decision making due to faulty,
   incomplete, or imprecise data.

   The expansion "Garbage In, Gospel Out" is an ironic comment on
   the tendency to put excessive trust in "computerised" data.
