They are best known for being super exclusive and elitist and looking down on those who follow the trends dictated by the mainstream.
They also seem to miss the entire irony of how they buy thrift store" clothing from department stores. Just feeding into the "mainstream" culture of consumerism that they claim to be countering.
But getting to the heart of hipster culture, it should be understood that true hipsters care a lot but they don't care. I.E. it’s all about the image. They spend obscene amounts of time calculating their outfits, the bands they like, and the hobbies that they're into. However, they have to pretend that all of it bores them, and that it comes naturally... because only the coolest hipsters don't try, yet still manage to be subversive and hip.
They also tend to be seen in obscure Indie concerts, in their own bands, being DJ's, owning or working at "subversive" yet lucrative businesses like t-shirt printing shops, chain smoking, shopping at Urban Outfitters or H and M, attending liberal arts colleges, or playing competitive dodge ball (because it’s so lame its cool)
if its "cool" its lame, and if its dorky its amazing!
Therefore the hipest things ever have to be Mullets, Knee socks, and Barney the Dinosaur!
"yeah, that little indie kid, why?"
"i saw her in a coffee shop they other day, reading The Brothers. She now goes by Anthurium..."
"Oh, our little indie kid has transformed into a hipster butterfly!"
Though early women evolved to prefer muscular, athletic, confident, secure men, hipsters are convinced that men who try to achieve these characteristics and their female admirers are doing so because they lack the intellectual capacity to realize that pale, sickly men with a smug attitude make the best partners.
hipster 2: I totally feel that. Oh hey the new iPhone 4 is out in stores!!!!!
hipster1: Oh! Em! Gee! i'm gonna call my mom and ask her for a check. Check your GPS for the nearest Apple store.....
average person: "oh..um.... i just like their music...because it's good....im sorry?"
hipster: *puts on fake glasses and walks away*
and finger-poppin' daddies:
Knock me your lobes.
This bit of hipsterism was written by "Lord Buckley" (Richard 'Lord' Buckley'), who was a singular, amazingly influencial (Caucasian!) comic genius that looked a little like Salvador Dali, affected a British accent, dressed in a tux and was best known as one who performed hipster interpretations/translations of well-known dramatic scenes and notable speeches.
The above quote comes from Lord Buckley's version of the very beginning of Mark Anthony's funeral oration in Shakespeare's Julius Caesar:
Friends, Romans, countrymen, lend me your ears;
I come to bury Caesar, not to praise him.
The evil that men do lives after them;
The good is oft interred with their bones...
