"The term "hipster" can be dashed off without a second thought and is accepted by most as a reasonable critique, even if those same people would bristle at the use of "dumb jock" or "geeky weirdo"."
"... it doesn't really mean anything. It's just bad rhetoric. At most, calling someone a hipster means that the target of your ire does something you don't prefer."
At least I wish we had another term for the fashion movement that includes fixed gear bikes and mustaches and skinny jeans, to separate the hipster-as-fixie-rider from the hipster-as-dismisser-of-things. (at most, I'd like if we could just stop hating. honestly, not like "har har don't be a hater".)
