Here are just three examples of a newish meme called "Hipster Barista" working its way on Quickmeme. Apparently, the "hipster barista" is many things: vegan, tattooed, an iPad 2 owner, a Groupon hater, and a fan of scarves. He also prefers "artist" over "barista."
Update: The hipster barista is actually real person: Dustin Mattson of Octane Coffee in Atlanta (click on "Staff" and the same picture comes up). According to the coffee shop's website, Mattson finished 5th place at the Southeast Regional Barista Competition 2010 and 27th place at the US Barista Championship 2010. He is also (of course) on Twitter at @DustinColeMmm. As far as his hipster cred goes, it is so far unknown.
Update #2: Eater Atlanta spoke to Dustin Mattson who said, "I do find it discouraging and disappointing that there was so much exposure brought to an attempt at making a joke of a culinary industry and the professional barista."
