Try being seductive, being the alpha male. There is a point where girls crave masculinity and not all of those fluff, childish converastions that even make the PUA sound gay. In other words, an alpha male is cocky and funny on a more mature level. Look at George Clooney and Brad Pitt in movies. They are very alpha-male like and also very seductive. But notice that they are seductive in a PUA manner. Meaning that they don't directly come on to the girl like the average loser would, but instead act seductive in a mean sort of way. So for example winking and then the girl saying, "I know what you're trying to do" and then the alpha male responding with, "Let's not get ahead of ourselves here+a normal comment."

Too many guys get the wrong idea about being seductive and instead act sexual in an AFC kind of way. Alpha males are seductive in a PUA way. Whenever you think PUA, think "douchebag."

Now trying to be FUN does work if the girl herself has had a very serious and boring day. That's just counter-intuition at work.

How have I learned all of this? Well I've tried being fun and cocky at the same time and the girl ended up saying that I talk so gay. Because I'd talk really fast, come up with these hypothetical childish situations where I would act cocky at the same time and so on. Then I looked at why REAL men still get girls without trying so hard and that was the answer-they don't try hard and are alpha males.
