Men?

Why is it that men feel the need to approach a woman with ‘game’?  Why can he just come up to you and say i like you can we go out?  Ive been approached by men who think ( i assumed because i am young) that i want to hear lines such as ‘yo mama i like it thick’ or some other wack line like that.  Why must you remind me of what i look like and why do you assume im not trying to loose weight and hence I wont be ‘thick’ for long?  Anways this is my rant and this is my question why are men like that?
