Guess the Wacky Word! A, B, C

Do you know the game Balderdash? Speaking from personal experience, if you play this game with the right kind of people in the right kind of mood, it can be utterly hilarious! You should really get it if you're into board games (and I'm not embarrassed to admit that I'm a board game kinda person :-) ). Anyway, I've decided to start a little online version of Balderdash :-) I'm going to look for weird, unusual words. The kind of words I've never heard before. I'll post several different definitions, and then you get to vote for the definition you think is correct!

PLEASE don't Google the word! That kinda defeats the point. Just take a wild guess, vote, and see what other people have picked. I will post the answers in the comments so you can see if you're right, so PLEASE don't look down there until you've voted!

Today's words are aeolist, bathykolpian and causeuse. The poll widgets are below for you to vote on. (If you're reading this post in an aggregator such as Google Reader, you may need to click through to this blog in order to see the polls.)
