as some of you know, I have a rather large collection of "obscure, abstruse and recondite" words. in compiling said collection, I have stumbled upon a subset of words that I have been unable to confirm anywhere. here are a few of them -- my undieing gratitude would go out to anyone (jazzo excepted) who can shed any light on any of these:

supradentulous - with a toothy grin?
catastarian - narrator? bearer of bad news??
suritorous - ?
ambigamous - will marry anything??
trobbisopdvan - huge shock caused by eating too many asparagus stalks?!
