Basti Says A bit of trivia for y'all

Basti Says A bit of triva for y'all.

The phrase "the whole nine yards" means "completely, the whole, everything" - eg: "I was mugged. They took my wallet, my keys, my shoes, my coat - the whole nine yards!"

The origins of the expression are unknown, but various theories are popularly held as to the root of it. One of the more common of these is that the expression dates from the Second World War, where the "nine yards" was the full length of a machine-gun ammunition belt, and to "go the full nine yards" was to use it up in its entirety. The expression, however, has only been dated back to 1966 (in US Air Force slang recorded in Vietnam) and it is unlikely it could have been in common use in the 1940s without being recorded either then or in the next twenty years.

Other suggested origins have included sources as diverse as the size of cement mixers, the length of bridal veils, the manufacture of kilts, the length of cloth bolts, and the structure of certain sailing vessels (where "yard" is short for yardarm, not for the distance).

I'd only heard the machinegun one before and it was around in when I went into the USAF in the early 60's.
