The term Skindawg originates in the East of England and refers to attractive women who can handle themselves and are quite mischievous. The Skin element is rooted in the ability to slap so hard skin is taken off the face, while the Dawg element is rooted in the subject traditionally having very good legs and a pert buttocks. This is a positive term, intended as a compliment and is used as an illustration of superiority in a group setting. To be the "Skindawg" is to be the best looking, most feared and respected woman in the group.
