Omg, it's saying good girls PREY because you get on your knees to prey. While they bend at the waist if they are being, in a non-innocence destroying term, provocative, therefore "bad girls". However I completely disagree with this...your religious doesn't make you a good person. Your actions do.
Actually, it's saying that all girls are good because they either slob on your knob, or present their goods to you for a good old-fashioned baby batter bonanza.
Pro "tip": The best girls bend at both joints.
