The Art of Manliness is a blog "dedicated to uncovering the lost art of being a man."
As such, it has a collection of posts like How to Ask For (And Get) A Raise Like a Man, Talk Like Frank Sinatra and this particular rule for dating called The Brad Pitt Rule:
Call up the woman you like and ask her on a date. Did she say yes? Great, she probably likes you. What if she makes up an excuse for why she can’t go out? This is the time to employ the Brad Pitt Rule.
Imagine that instead of you, Brad Pitt had asked this same woman out. Would she use the same excuse with him? If Brad Pitt asked her on a date, would she still say she had to study or was going to the movies with friends that night? Nope. She would have dropped. pretty much anything and everything to be able to accept a date with Brad.
Now you’re not Pitt obviously. But if a woman is interested in you, she will drop her other plans to be available to go out with you.
Of course there are exceptions; the woman may have a legitimate reason she cannot make the date. Perhaps she has to work or go to a funeral. But, and here is the real clincher, she will suggest a different time for the date. She will say something along the lines of “I can’t do it Saturday night, do you want to hang out next weekend?”
If she makes up an excuse and she does not suggest an alternative plan, you have been shut out. She is not interested. Do not ask her out again. Doing so will only result in awkwardness and you feeling like a tool.

Ladies, sometimes it is just best to be blunt. We guys don't get subtle hints. Instead of being nice and having us try to "read between the lines", you just have to be mean. Most of the time, if you make an arbitrary statement, the guy will still interpret it as being positive, and will continue to ask you out. A simple "I'm sorry, but no" will suffice. It saves you both some time and stress.
Shyly, apologetically, she answers, "Yeah.. probably more like one in a million..."
The realization dawns on the poor hero. "So.. what you're saying is.. there's a chance!"
For most men, not blessed as Mr. Pitt, it's not so much about winning her over.. as wearing her down. It's a different kind of staying power.
On the other hand, I find that women don't understand this when i'm the one who's 'busy'.
