It's "rawgabbit". It means "Someone who speaks authoritatively about something they know nothing about." I give it freely; use it as you wish. I, ahem, have no use for it of course.
I ran across that handy bit of linguistic treasure here along with a few other old English words whose numbers have been retired. There is some lovely stuff here. Although, I do think someone has accidentally switched the illustrations for snollygoster and anon. (And by the way, what's so antique about anon? I use anon all the time. Hmm? Oh. Yes. I see your point.)
