Well i think i'll start with my experience of chavs.
My story:
Im not sure how long chavs have been around, because im not sure if they "existed" when i was in primary school, you dont realise them at that age. Those where the days of my life.
When the time came to move to secondary school, everybody was so exited, because when you are young you are encouraged to act mature, and its great when you become a "big boy".
The first month of secondary school is quite exciting, you meet new people (only the new ones like you) and share interests. Then, out of the blue, it becomes trendy to say certain phrases, and these start spreading round the playground. Naturally, everybody did it to fit in. After that, more things come in, like listening to rap is cool. When i first heard rap/garage (chav music), i kinda liked it, but i think i was liking it on purpose because everybody else did. I never bought an album though, i just stuck with my usual taste in music. Year 7 goes past.
Now in year 7, you never realise how" lary" you actually become, but in year 8 you do, when the newcomers arrive, they are the most loud-mouthed people i have ever seen. It made me sick, and after this, i changed my ways. I watched as everybody else made the gruesome transformation into chav-kind. I got on with most people, but i steered clear of turning into chavs.
I moved to Spain in year 9, and it was cool. I made non chav friends and was enjoying life there......for a while. We had a rough time over there, with family members dying etc. and i slowly realised how boring it was out there, but i had friends. I stayed for 2 years, and then came back last summer.
The horror....i returned to school in year 11, and i couldn't describe it any better than "chav-land". There are few people like me, and we are friends, and we try and keep clear of the scum. If we do, we try to outsmart them. Luckily, the 6th formers, who are older, are not as idiotic, and are not chavs, so i am not concerned with coming across older chavs. I dont have problems with chavs, but they piss me off to the extreme. I get the odd inslt like any, but i just fire back, and use most of the time with my incredible wit :P
I dont go out much these days, which doesnt really make me unhappy, but if it wasnt for those bastards i think i'd be happier.
P.S. Girk chavs are the funniest things ever, cause of their stupidity. They are easily handled :P
