As the story goes, Gosling suggested the phrase during an insult-brainstorming session with inhumanly intense director Nicolas Winding Refn, but here's the thing. Says Gosling:
They were trying to come up with terrible things to say, and what was the worst thing you could say, and there was a long list of options, which they came up with, too, which never hit the newsstands, thank God. But Kristin got it wrong. I said the worst thing you could call someone was a 'dumb hipster.'And, gasp.
This is unfortunate for Brooklyn, being the mecca for dumb hipsters according to many of the Internet's best and brightest commenters. And now it's the very worst possible thing you can call a human being. Ryan Gosling said so.
It's as if those commenters knew all along...
