Here is an example of the problem as I see it. There is a good-looking man who is well aware that he is a good-looking man and has been trading on that fact for years. There are other men around, smart, strong, competent men some of who are also quite good-looking. If you ignore the obsessive lazy pretty-boy, the other ones will begin to take you seriously and talk to you. The problem is that the obsessive lazy pretty boy will then tilt at you like a damn wind-mill and make you his One True Mission in life. The question is, what is a tried and true way to send the obsessive lazy pretty-boy packing?

A knee to the crotch usually works.
