as an alternative, I propose diseuonym

I never look at topics that go to five pages, but here I am, it's 5.30 at work, I'm restless, let's load 'em all up. A diseuonym should be a caconym. 'Diseuonym', is a terrible word for it... oh wait...

Dis and inept (not *inapt, lesson on Old Latin stress available on old request) are Latin, onym and eu and caco are good Greek, and fiercely proud of it.

Anyway, I'm here because I came across a good one recently: bellibone. Spenser used it to mean a fair maid, belle et bonne but that's not at all the mental impression I get.
