Everything is much easier: "good guys" is such a politically correct definition for those male representatives who have nothing to praise at all. Beautiful is characterized as beautiful, smart is characterized as smart, cheerful and the soul of the company - as cheerful and the soul of the company... in general, any quality will sound in the definition. And when there are no qualities, but not to call a person any (although he is not beautiful, but not ugly, although not clever, but not a fool, etc.), the abstract is pronounced to the rescue. As good as he is, he does nothing bad. True, with a girl because of its complexes, most likely, will be jealous paranoid, considering fictitious accusations as a sign of indifference, but at the stage of dating it is poorly identified (unless you get a clinical case of a good guy, who will be brought to watch a mom or a aunt or who will build a conversation in the spirit of "I am unpopular with girls because I have an iPhone and a passport machine is not there, babies are useful creatures, I hope you are not such, oh, and you where, so out of knowing, all the babies are the same, because I have an iPhone is opened..." - but usually they are still smarter and not immediately so burned).

By the way, in fact, they are quite popular with the category of girls "only married", they just prefer to avoid these girls themselves.
