A combination of hipster and poseur.
So stated due to the recursive levels of irony present in many a hipster.
-"Yo, is that guy a poseur or a hipster? I mean, is that John Deere hat actually worn unironically with those Carhartts and Budweiser shirt? I mean, it's on straight, with a bent brim, and his workboots make it look like he might actually work."
-"I don't even know anymore, bro. We're in Williamsburg; how often do you see working types at a trendy latte shop like this? Let's go drink some Night Train."
-"Yeah, he's probably just a hipsteur."
