Men are competitive by nature. Whether it is in sports or earning a living and enjoying an upscale lifestyle or anything else, the only variable is how they keep score. This is no different when trying to understand why men seek a trophy girlfriend. It is simply a way to show the world that they are successful. Having a beautiful woman on his arm is like a billboard saying that he has arrived. The Trophy Girlfriend meaning is not about a long term commitment or relationships (though it could be), it is about tell the world he is a winner.
