Answers: that wet stuff inside the vagina when girls get horny.
I can't find a specific name for the lubricating fluid with a casual search ... but here it a good place to start:
"The lubrication fluid contains water, pyridine, squalene, urea, acetic acid, lactic acid, complex alcohols and glycols, ketones, and aldehydes. The fluid is typically clear and more resembling of male pre-ejaculate than male ejaculate. It can vary in consistency, texture, color, and odor, depending on sexual arousal, the time of the menstrual cycle, the presence of an infection, and diet."

The thing that is wet that can make a girl moody during certain times is called the menstrual period but she can start to get moody about a week or two before her period. If the moodiness is so severe though she should see her doctor for further evaluation of the situation to see what they think is going on.
