well, its from a job i used to have selling mobile fones in its boom, to do with people getting a free fone on a contract, using it rather alot before the first bill is due, then selling the fone on ebay, and doing a runner! it used to happen a fair bit in bigger cities, but often not to me, anyway, these fones were known as 'kaners', because you would kane them before the bill was due, and the dog bit is rhyming slang. the 1x1 bit is yahoo mails fault. theyt told me [email='kanerdog@yahoo.co.uk]'kanerdog@yahoo.co.uk[/email]' was taken but 'kanerdog1' was available, so i got wise, asked for 'kanerdog1x', they no, thats taken, you can have 'kanerdog1x1', thought this was cool, as i rode a singlespeed, works for me.....
