This NYT article is about the perils and positives of two men spending time together without the crutches of either sports or business.

An excerpt:

Anyone who finds a date with a potential romantic partner to be a minefield of unspoken rules should consider the man date, a rendezvous between two straight men that is even more socially perilous.

Simply defined a man date is two heterosexual men socializing without the crutch of business or sports. It is two guys meeting for the kind of outing a straight man might reasonably arrange with a woman. Dining together across a table without the aid of a television is a man date; eating at a bar is not. Taking a walk in the park together is a man date; going for a jog is not. Attending the movie "Friday Night Lights" is a man date, but going to see the Jets play is definitely not.

"Sideways," the Oscar-winning film about two buddies touring the central California wine country on the eve of the wedding of one of them, is one long and boozy man date.

Although "man date" is a coinage invented for this article, appearing nowhere in the literature of male bonding (or of homosexual panic), the 30 to 40 straight men interviewed, from their 20's to their 50's, living in cities across the country, instantly recognized the peculiar ritual even if they had not consciously examined its dos and don'ts. Depending on the activity and on the two men involved, an undercurrent of homoeroticism that may be present determines what feels comfortable or not on a man date, as Mr. Speiser and Mr. Putman discovered in their squeamishness at the Modern.

(Note: Matthew Speiser, 25, and John Putman, 28, were college classmates. They went to an art show together at the Museum of Modern Art but semi-avoided each other while there and didn't talk publicly like they knew something about art -- which they both did.)

Jim O'Donnell, a professor of business and economics at Huntington University in Indiana, who said his life had been changed by a male friend, urges men to get over their discomfort in socializing one on one because they have much to gain from the emotional support of male friendships. (Women understand this instinctively, which is why there is no female equivalent to the awkward man date; straight women have long met for dinner or a movie without a second thought.)
