Meaning: a long or tedious sermon; also a piece of doggerel, a rhyme.
Usefulness: 1 (I was asked for a word to describe the "You wouldn't steal a car..." blurb at the beginning of most videos these days; while nominy captures the moralising tediousness, it lacks the compulsory element. Can obviously be used in a number of contexts: "Not another nominy, George: we've heard enough today.")
Logofascination: 1 (Possibly from in nomine patris... at the beginning of sermons; that's probably about all that was retained of sermons delivered in a drone or muttered in a monotone.)
