Young black activists roared their approval when Barack Obama recently greeted criticism on the trail by dusting off his shoulders, a reference to a rap song by Jay-Z called "Dirt Off Your Shoulder." The media covering the moment went crazy, too. Washington Post reporter Teresa Wiltz hailed Obama’s moves and called it a "seminal moment in the campaign, the merging of politics and pop culture," and noted the lyrics suggest "If you feelin’ like a pimp...go and brush your shoulders off."

So Barack Obama is feeling like a pimp?

Online at "The Root," a Washington Post website for African-Americans, Obama supporter and Princeton professor Melissa Harris-Lacewell was sky high. "Like every other hip-hop generation voter in America I went crazy when he did it," she wrote. "I almost couldn’t believe it. It was a perfect moment."

Harris-Lacewell read that moment as a sign of racial swagger and solidarity with "his base of young urban brown and black voters" and they loved it. "He displayed all the familiar self-assurance and bravado of the hip-hop emcee. The people who got it went nuts, while those who don’t know hip-hop just thought he was being funny and confident."

The video went viral and became a YouTube sensation.
