"Dude, remember sarah?"
"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!"
A hipster is very similar to an Indie Kid. Hipsters generally are snobbish, holier-than-thou sorts of people. They tend insert non-sequiturs about pop-culture into everyday speech, as well as obscure music references, and comments on political goings-on. They're quite fun if you get to know them, but be from another label and you might be snubbed. They frequent coffee shops and the salvation army and know more than you ever will or would hope to about... well, pretty much anything obscure or remotely creative/underground-culture-based.
1: Did you see her shirt? I bet she got it at the salvation army.
2: Oh, yeah, thats that Hipster that works in that coffee shop. She's a bitch, but she's cool.
Not to be confused with the other (incorrect) definition of alternateen (which actually is an umbrella of Punk, Poserpunk, Emo, Scene, Goth, Hardcore, Grindcore, and Death Metal, all in one tight little generalization), Alternateens are the undereducated Hipsters. They look relatively indie, but stay within earth tones, have close to hippie-esque hair, and tend to say they listen to "Alternative Music" not knowing the specifics of the genre. Alternative encompasses all subgenres of rock (see whats above, give or take some). Alternateens are mostly found in small towns and are teenagers that try too hard with knowing so little about culture.
We were walking down the street in that tiny port town when we passed a teen center surrounded by Alternateens, who gave us the nastiest look.
