Sklabby is the combination of skinny and flabby and refers to women (usually European) women who are skinny and yet also out of shape. In America you typically find two exremes - women who are either big and fat, or women who are skinny and in great shape. In Europe, you won't find many women who are terribly fat, but you also won't find many women who are terribly fit either. A chick may have a small ass, but it'll be jiggly ass - skinny and flabby.
