I get in trouble for my long hair (not that long in my opinion, only shoulder length), but it's generally not chavs, usually it's my girlfriend... it gets up her nose and in her face when we hug, so I'm looking to get it cut... that sort of problem I'm ok with, that's a practical thing.
As for chavs though, I now generally disregard anything they have to say as it's generally stupid. I don't like to generalize people, but chavs... well, I've seen a lot of chavs do and say some pretty stupid things.
Like when I was on a bus, and a chav spotted a German flag and said to his chavvy mates (and everyone on the bus) something about wanting to pull it down and pee all over it... then it got really retarded, the conversation between him and one of his mates went something along the lines of:
'Why? What have they ever done to you?'
'Erm, how about killed thousands of us english?'
'I can't believe you're going on about world war two, that happened years ago'
pause
'I wasn't talking about world war two, I was talking about world war one'
'Oh. Did we fight them in world war one? Oh, well I don't know my history too well'
So many levels of stupidity captured perfectly in that moment... It always makes me laugh
EDIT: I don't mean to derail this thread with tails of stupid chav moments, I just thought I would share this moment with you all before I forgot about it again for a while
