Not sure if I've spelled biffter correctly - one f or two ff's. I've taken it to me something like "the whole nine yards" and in a reference to a full breakfast as in "we had the full biffter" meaning there were eggs, potatoes, bacaon/sausage/ham. A friend of mine from Scotland was familiar with the term but we were never able to track it down. Thanks.
The latest edition of Chambers Dictionary offers bifter or biftah and exactly the same definition as I gave three years ago in Buildersmate's link...a spliff. (I don't believe it was even IN the previous edition.) And the link I provided back then offers further hints as to the source. I can't vouch for any of them.
