Personally, I agree with the DA, but there is also the story that it is a corruption of "Deluxe Box". Many years ago some thing (might have been Meccano or something like that) was sold in a "Standard Box" and a "Deluxe Box", the deluxe being the best there was.
Anyways... The DA, you seem like someone capable of considerable logical feats :J so maybe I should refrain from informing my AB friends that I'm not you - or you're not me... But I feel they should know.
I like your alias - kinda envious of it now...
Postdog, your box story has a true ring to it. That's the way things really do come about.
yes I heard that recently, its from Meccano, they had
"Box Standard" and "box Deluxe" on the packaging, thus by corruption we get, 'bog standard' and 'dogs ********'.
