creeping featuritis
/kree'ping fee'-chr-i:`t*s/ n. Variant of
creeping featurism, with its own spoonerization: `feeping
creaturitis'. Some people like to reserve this form for the
disease as it actually manifests in software or hardware, as
opposed to the lurking general tendency in designers' minds.
(After all, -ism means `condition' or `pursuit of', whereas
-itis usually means `inflammation of'.)
