okay where do i begin? we could start off with a hearty insult to everyone who uses this word... you bunch of flare wearing hippy scum. It seems that over the last few months, chavs have forgotten the insult 'grunger' and replaced it with 'ur mum!' its a shame really.. because the poor chavvie sods deserve at least to be able to finish thier own sentences... oh the wonderful days where i have spent walking along the road and all of a sudden, in a blur of nickelson tops off of the nearest market stall, AND FAKE BURBERRY.. my mum is being cussed (or so they say anyway) by a group of ppl pronouncing that i own a parent... oh well, i guess we cant all be genetic and social deformaties born in test tubes.. love u all! ur mums!
