When a girl thighs are thick, but not fat. Also make for great cusioning during intercourse. This is usually how they are best identified. Most girls that have these have a relativley bigger than average figure yet their weight is proportional to their height and are not fat. Other girls that have these are just chubby chicks, but not too chubby, because thats when you get into cottage chese thighs. And of course last but not least, a girl who plays soccer will have these thighs, and damn they will be sexy. See Also thick thighs.
That girl has soccer thighs, I could tell once her pants were down.
