Profectitious

Meaning: from a parent or ancestor; originally of dowries from a father or other male ancestor.

Usefulness: 2 (can be used to describe family habits - my cricket addiction is profectitious; compliment babies politely - his nose is positively profectitious! - or to describe assorted mining and media dynasties. Or, of course, trustafarians.)

Logofascination: 2

Barytonize

Meaning: The OED lists this as a word but does not define it; I shall write and complain.  In context, though, it's pretty clear we're talking about farting. Deep, profound, musical flatulence; sums up most of Rabelais, really. (Context below, if you don't believe me)

Usefulness: 1 (Particularly of meetings. To be exactly confusing you could say "This Urquhartian barytonizing must end. I call for a vote!")

Logofascination: 3 (juvenile fascination: 1)
