Works, but people misinterpret it
DeAngelo's concepts are on the right track, but a lot of people misinterpret them.
They think he's saying just to be an arrogant azzhole, but that's not the point of it, though a confident, arrogant azzhole will get more throwaway sex than a meek, asexual "nice guy," all other things being equal.
DeAngelo's main points are: be playful, be sexual, and be a man. Also to present yourself in the most attractive way possible, and not overwhelm a woman with attention (unless it's a matter of "striking while the iron is hot).
