Get yourself a scooter and fight back the chavs... just steal one of theirs!!
Obviously this won't work if your 16-19 and a chav yourself...
And yes.. this is a joke... please don't post back saying how that would be lowering ourselves to their level etc!!! I'm just bored so I thought I'd post!!
I can't imagine buying one being any more expensive than renting one for a few months. You can pick them up cheap, pay insurance monthly so you can cancel, then flog it afterwards.
