Last week President Bush chest-bumped an Air Force Academy grad, a moment that was captured on camera and circulated far and wide across the Internet.

Now the Obamas have done some bumping of their own.

On Tuesday night before Barack Obama delivered his victory speech in St. Paul, Minn., he and wife shared a fist pound (also called a dap) on stage after which she gave him a thumbs up. Obama told NBC News that that moment really summed up their relationship.

“It captures what I love about my wife, which is that there is a reverence about her and a sense that for all the hoopla that I’m her husband and sometimes we’ll do silly things,” he said.

The Web is heating up with comments on the simple, but potentially telling gesture.

“I would imagine to a young voter, this was another sign that these people are one of us,” psychologist Drew Westen told the New York Daily News. “People saw their willingness to display their affection in the way they really do — at home or in private moments.”

The New York Magazine wrote, “Not only does this intimate gesture between Michelle and Barack Obama, exchanged on Tuesday night in front of thousands of fans, indicate they are sort of hip; it also tells us that they love each other.”

But some of the commentary is on the media’s commentary itself. Slate.com writer Christopher Beam put together a collection of how different news outlets referred to the “pound.” Among his findings…
