Steve,
She means that she'll go to a climbing route and climb it sight unseen. Doesn't ask anyone for conditions or study the climbing route. Basically, she's able to walk up to a wall, look up, and solve the puzzle of how climb up face/crack, whatever it is, on the spot.
Google 10a and you'll see what a route like that looks like. It's difficult to say the least and waaaaaaaaaay out of my capabilities. The fact that she's able to do it at all, nevermind not getting info ahead of time, makes me puzzled that she has such a hard time with the Mountaineer's Route.
