Humm... It could also mean "boobjob alert"
To answer your question, personaly I'd step out of gaming for a moment. You already have a reputation as a player, so PUA SOP will not do you any good, it will just be more of the same. Get her off-balance by saying what you really want to say. Personaly, I'd simply ask something like: "Everything was fine and now you blocked me out of nowhere. Care to explain? I think I deserve at least that."
If she goes for it, you have a chance to mend fences and get on her good side again. If she does not answer, just cut her off.
Assuming you have to (or want to) cut her off, when you see her on the street if she comes talking to you, be cool but civil. Don't make a scene but also make sure she gets the point that you do not care for her anymore. If she ignores you, ignore her too.
