The highest level of swag possible. Only one girl in the world has the ability to pull it off. It combines the suavest of movements with smooth talk and a sophisticated manner. You need to 'holla atcho boy' when you see this kind of swagger. You'll probably only see it a few rare times in your life, if you're lucky.

Tyson: "Ohh ya mann, I know. She's my dream girl, but with swag like that, she's wayy outta my league."
