Preps are the kind of people that value money more than anything else. They will double cross their friends creating drama for no reason.

Plain and simple, they're a band.
Made up of Joel & Benji Madden, Paul Thomas, and Billy Martin at the moment.
Like any normal people, they shift and evolve in their styles and such. It's human. Each of them has a rather distinct fashion, ranging from brilliant liberty spikes to shiny hip-hop get-ups.
They're being themselves, exploring their tastes and enjoying themselves, trying on every look just like you did in front of your mirror. For GC, though, we're the mirror.

They're not poseurs, because they're only claiming to be Good Charlotte. Indeed their musical style's just teeming pop and punk and whatever. It's not quite so condensed into such nimrodical labels.
True, they sing about sucky lives while right now we'd all like to be in their place in a happy little mansion-type place, but they did used to be living their words. It's not like they've completely ground out all memories. They can relate to so many, because countless people these days lack money, lost a family member, whatever. It's not like you'd go and continue sitting in a cardboard box (hush up, obviously an exaggeration, don't jump on me yet) if you had the chance to totally improve your lifestyle just by doing what you adore.

No, they're not just MTV clones for preppy losers. I only know perhaps three people who like Good Charlotte. Everyone else simply despises them. And out of these people, I only know one closely -- one of the others, I know, used to be lovely and herself and rather preppy...

Gothic people are just like everyone else. They just express them selves differently. Just because they don't look the same as you and me doesn't mean that they are crazy or anything. They are normal healthy people and should just have the chance to talk to people different from them if they want it without being looked at like a freak, or treated like a jerk.

One that does not betray a friend and remains unmovable when everyone else does.

Calling someone a poser is:
1) a right of passage for all "emo" kids
2) stupid... no one truely thinks for themselves anyway, even the most "original" probably got it from someone else and/or someone else has already done it
3) equal to myspace, everyone is doing it because everyone else is doing it, and now we are stuck doing it

In addition to the accurate definition below, the reason that these girls are doing it all lies in the fact that they are completely insecure and so desperate to fit in that they create a transparent, fake way to SEEM unique, separate from those around them, and deep to everyone else. If it were real, and genuine, then they wouldn't advertise it so blantantly to EVERYONE around them. The fact that they broadcast this image is, in itself, evidence of this other motive. It's really just another manifestation of the teenage insecurity/struggle to find oneself and make a certain impression.

Someone who is from Britian (ie Scotland, England, Wales. NOT Northern Ireland, as Britian and the UK aren't the same.)

They actually spell honour and colour correctly, as that is how the words are spelt in their language. The Americans don't incorrectly spell color and honor, because that's how they spell it in their language (contrary to popular belief, Americans don't speak English, they speak American: a bastardization of the former). Oh, and English isn't the only language spoken in Britian, what about Welsh?

A Brit has a unique sense of humour which they often resort to at solemn times. They're basically exactly the same as everyone else on the planet, except for small differences.
