What does the following quote mean from "Romeo and Juliet": "...but, like a misbehaved and sullen wench"?

The quote "Like a misbehaved, sullen wench" would be a comparison of the character to someone who is sulking, who likes to act up, who is often in trouble.  Someone who is sullen is sulky, sort of angry and ticked off.  Therefore, someone who was behaving "Like a misbehaved and sullen wench" is being a troublesome, sulky, pain in the butt.  :-)
