Per Wikipedia: "Bloke is a British slang term referring to a fellow, a man. It was first recorded in England in the 1820s and appeared in a glossary by the late 1830s, spelled "bloak" and defined as "a gentleman." During the second half of the 1800s, it had fairly common usage in American English, from underworld slang to more general use but has been little heard there since the 1930s. Its origin is unknown but It is sometimes attributed to a private language spoken by the tinkers (or travelling people) in Ireland."
Per the Accurate and Reliable Dictionary "some: Definition: remarkable; "that was some party"; "she is some skier"
Wot that geezer meant in referring to me as some bloke, was that I am a remarkable gentleman. While modesty precludes me from commenting, honesty precludes me from denying this online assessment (see this is not straying off topic, Chris) of my character.
Meantime, one hopes that fellow posters did not have too many Britney Spears over the festive season, such as to cause a Ben Dover, that they all have a good new Donkey's Ear, in which the Sherman Tanks will not cause too much world Soapy Bubble, keeping off the Tom and Dick, devoid of Plymouth Argyles, while making loads of Becks and Posh despite wordwide state of boracic.
Be lucky, mates.
