I'm an (rabid football fan and player) American from California, and work with a lifelong Villa supporter - he referred to City supporters as 'blue noses,' but won't explain further. He hinted at some less than PC definitions, maybe rude, or ???, but won't explain. Of course, the more secretive he is, the more that I want to know! Here in the states, a blue nose is a kind of prude, somewhat priggish and maybe snobby. Obviously I understand the local derby rivalries, etc; well, but am unable to get any more information here - and google references 'blue noses' quite a bit, but no real explanation other than a couple items stating that Birmingham City fans are called 'blue noses.' Can anyone enlighten me? Obviously I don't want to incite flaming, and promise to not take sides, but I'm really, really curious. cheers all!
