For some guys it's cars, for some it's watches. It's kinda weird seeing the men of my generation run around trying to find their "X" for "Yeah, I'm the <X> guy. Impressed?"
I wish the men around me didn't choose cars for how much noise they make, I live on a somewhat busy street.
I used to be harder to find people in to a specific sub-culture but now it is easy to find a subeditor or whatever. They just feed off each other until they are insufferable.
Beer, mechanical keyboards, watches, whatever.
