Riddle: Some more word play

The English language is fascinating to me and I learn something new quite often. I think the fact that it is an amalgam of so many other languages, some closely related and some not, that makes it a truly powerful language. Anyhow, I heard a word the other day that is not widely used or known. I have probably never used it in casual conversation but do appreciate the meaning.

Can you name a word containing 4 consecutive vowels whose meaning is an adjective for being a kiss-ass?

Can you name another word containing a pair of consecutive vowels, repeated consecutively and whose only other letter is found in the word above?

Please refrain from answering in the comments until I have posted the answers in the answers page. BTW, the last two riddles have had their answers posted.
