- noun Abbreviation for 'contrived acronym term'. A name is
a CAT when it consists of tortuously implausible letter
assignments in an effort to construct a real (or at least
pronounceable) word. The name MUD is an archetypal
CAT, as are
MUG, MUSE and most other MU* derivations. Unsurprisingly, CAT
is itself a perfect CAT. Compare CAB.
