I just wanted to point out that everyone is different and so is every situation. One of the worst things you can do on this site is try to apply advice that doesn't fit with you personally. For example, if you're not a jerk by nature, unless it's completely obvious your joking, don't try so hard to act like one! What works for one person does NOT work for everyone.
As for the large list posted earlier in this thread, I agree most of those things should generally be avoided. I disagree with some, however. I definitely think there are some times when you can compliment a girl for being pretty; many find it flattering. Also, I don't think it hurts to imply how thin she looks at times. My point is, that everyone has a different style and, believe it or not, so do girls. Don't shoot yourself in the foot by trying too hard to follow these "rules." They are not set in stone. Think of them as tips that you should take with a grain of salt.
I have never understood why a lot of women are turned off by a guy asking them out or texting too much. If a girl finds a guy attractive, funny, fun to be around then stuff like that shouldnt matter.
A lot of the times, it just shows desperation, which is never good. Desperation is the result of something else where you're lacking, be it social skills or confidence or whatever. Many will think "Doesn't this guy have anything better to do than to text me all the time?" or "This guy must be really into me" (many times, resulting in the end of the thrill of the chase)
