It's actually not pejorative. (The term "wenching", however, is. Go English language! :)

It's not the most fortunate choice of title, but given that they're trying to create a pirate context - I'm not sure it's worth getting too upset about.

(And please, before somebody wants to throw sexism accusations my way, do check my posting history :)

Edit: I stand corrected. If urbandictionary is your source of what language means, it is pejorative. Interesting. I wonder if Vanessa was even aware of that.
