Indiekids come in all forms and fashions. What seperate them from the flock is their sense of entitlement and the belief that they are, in some way, smarter or more enlightened than their peers. Often this sene of superiority stems from their taste in music.
They will smugly admit to having an "eclectic" or "alternative" taste in music, but what they really mean is that what they listen to is better than what you listen to. If confronted with bands they have never heard of, they will vaguely dismiss them and run home to check them out on Pitchfork.
Indiekids will claim to read books, but are often simply reading reviews or lists of books compiled by other indiekids. When fouled up in a conversation about a specific book by a four-eyes or member of the literati, the indiekid will claim that they are mixing up plots, characters or details with other books they have just read. If not pressed on the matter they will become offended and ragequit.
Fond of irony, but lacking the ability to define what irony is, the indiekid is often at a loss when having a tête-à-tête people who use the word ironic ironically.
Indiekids may later evolve into hipsters or scenesters.
Joe: "Hey, you hear the new Bloody Beetroots album?"
Indiekid: "No, well, of course I've heard it, but I just didn't feel it. Too commercial and well-polished. Plus I've really been getting into IDM again lately..."
Joe: "IDM? Never heard of it."
Indiekid: "Oh, that's no surprise, it stands for Intelligent dance music."
Joe: "Oh for f*cks sake."
