I've found that no mater what country I've been to, or what social classes the people belong to, three topics have a 95% success rate when it comes to social relations with guys: sports, cars, fishing/hunting. And to some degree handywork. It is a bit unfortunate, as I'm not at all interested in talking about those things - but they are such staple topics, that you can come off as a sort of outcast if you can't keep…
Sports and cars is more common with the older generation, but anyone below 35 will probably be uninterested, unless your circle is finance or blue collar work.
