Quite a lot of things, really. "The guy with the piercings" shows up some (I've got a handful scattered around my ears and face), as does "that guy with the hat" (my black porkpie hat, complete with pheasant feather), "that guy with the goatee and the tight jeans" (So I cultivate a bit of a hipster aesthetic. So sue me.), and more often than any other, "that guy who--oh Jesus, you're tall." (I'm almost 6'6".)
So yeh, I guess I accumulate these little titles.
