n merry event where people get together in a field and sell the rubbish from their attic, under the secret suspicion that some part of it might turn out to be splendidly valuable. Not entirely dissimilar to a jumble sale. The term stems no doubt from the fact that this is normally carried out using the boot of your car as a headquarters. This sort of nonsense is now largely replaced by eBay, where you can sell the 1950s engraved brass Hitler moustache replica your father was awarded for twenty years’ service in the post office without actually having to meet the freak who bought it.
