A good time. Women like men who entertain them. They like men who seem mysterious or dangerous, because those men are the ones they feel will be the most entertaining to be around.
This is why you see women do stupid shit like let a terrorist go free so he could take her to Syria. To a man, this sounds like utter stupidity. Release a terrorist just so you can travel to a war zone full of brutal thugs, all in the company of a convicted murderer? To a rational person (i.e. a man), this sounds stupid. But to a woman, it's an adventure with a rough, scary man.
In other words, the stuff female wet dreams are made of.
This is also why the "bad boy" stereotype exists.
When dealing with women, I've found the best way to approximate the female point of view to be to ask yourself "what would I think of this situation if I had no ability to think logically and was entirely focused on spur-of-the-moment decision making with no consideration of long term consequences." This method of thinking is essentially how women think, so if you approach dealing with women from this perspective, you'll be able to get inside their heads pretty easily.
Basically, do crazy shit. Drive fast cars. Get into fights. Go out drinking. Act like you're only living for today and that your greatest ambition in life is to make the biggest, most obnoxious mess you possibly can.
Women don't want that. Sure, they may say they want a "nice guy," but if you ever tell them you are a "nice guy," their pussy will dry up faster than a puddle of water in the Sahara. They view "nice" or "caring" men as desperate.
Women like being toyed with. They like a man who hardly ever notices them, who barely gives them the time of day. They like a man who is always busy with other stuff, and feel compelled to pursue him. They like a man who doesn't quite view them on the same level as himself (i.e. be an arrogant bastard). Don't explicitly say that you're better than them or act comically cocky, though – that makes it look like you're trying too hard and compensating for some insecurity. Just casually act like you don't give a shit about them or their opinions. Don't give them any more attention than you have to.
Of course, this only works if you're reasonably attractive. The attractiveness gives them the initial reason to notice you – without that, they'll just ignore you and not care how aloof or "mysterious" you seem. The attractiveness is the hook, and the devil-may-care, reckless attitude is what draws them in.
However, attractiveness doesn't necessarily mean "good looks." Attractiveness is a composite of looks, body (i.e. get /fit/), money, sense of humor, etc. Basically, attractiveness is anything that sets you apart from the 3.5 billion other men in the world and makes women notice you.
