I seem to remember Sir Humphrey in Yes , Prime Minister, referring to a comment that Jim Hacker as made as a "epitaph that could not be assigned to the report of event that had occured" - I think the specific word was "true", such it the nature of english to mangle phrases in certain places beyond that which the OED / Chambers might have normally recorded ( At work we used to refer to normal Coca-Cola as "Full Fat" , when doing the daily sandwich man order for the office, and the caffeine free as "Unleaded" - maybe I just worked in an odd office but it seemed to happen in at least two different employments 80 miles apart)
