In some ways, the 'bro' is not new. He's there, for example, in Philip Roth's "Goodbye Columbus" as Ron Patimkin, the big athletic empty-headed brother of Brenda. What's different is that in the 1960s, it seemed fundamentally untenable to be Ron for an extended period of time. Ron only really made sense as a college athlete, and now he's stuck with a bunch of mannerisms and interests that seem vaguely out of place. Today's bros -- these are the guys with the popped collars, the backwards baseball hats, the high fives and the far more cutting edge handshakes -- seem determined to carry the vibe of college -- drinking games, video games, treating sexual conquest as a game -- forward toward their thirties. This is also not a new idea, but rarely has its tribalism been so easily spotted. You can join the conversation - email firstname.lastname@example.org or tweet us @wnprcolin.
