elephantine: adj. Used of programs or systems that are both conspicuous {hog}s (owing perhaps to poor design founded on {brute force and ignorance}) and exceedingly {hairy} in source form.

:elephantine: adj. Used of programs or systems that are both
conspicuous {hog}s (owing perhaps to poor design founded on
{brute force and ignorance}) and exceedingly {hairy} in source
form. An elephantine program may be functional and even friendly,
but (as in the old joke about being in bed with an elephant) it's
tough to have around all the same (and, like a pachyderm, difficult
to maintain). In extreme cases, hackers have been known to make
trumpeting sounds or perform expressive proboscatory mime at the
mention of the offending program. Usage: semi-humorous. Compare
`has the elephant nature' and the somewhat more pejorative
{monstrosity}. See also {second-system effect} and
{baroque}.
