When a girl swings her leg up as high as it can go on top of something and solicits sex. She usually props her leg on a bar table or chain fence with her junk hanging all out, so they can see inside her vag, and then solicits herself for sexual services.
Catherine keeps doing THE DIRTY CASTANON to me. Her leg was right next to my face and I could see straight into her vagina.
