Why girls love rude guys?

This is coming from a girl. No girl will like a guy who's too pushy and bad-boyish, but a guy who seems cool and confident and who can sweep her off her feet will make her excited. If you are looking for this kind of approach with a girl, then your going to have to know what your doing. Get her worked up and excited about you. Carrying her places and spinning her around is a great way to excite a girl.

Women are biologically the "weak gender", so, as in wild life, women want an alpha male, a male who can protect her and their offspring. So a man who is rude tends to let people know he's the one in charge and will probably be better at protecting mother and children and provide comfort and a good life.
