The English paper, The Mail, reports on a survey of 3,000 adults commissioned by UKTV relating to the reality of baby boomers' experiences during the 1960's, 1970's and 1980's relative to what they may have told others more recently. The article says that "the study revealed that 34 per cent of those who grew up in the Sixties admitted having embroidered their past to gain the respect of friends and family. Of these, a quarter claimed they were flexible with the truth so their children would think they were 'cool'.' The Mail labels this behavior "generational gazumping" -- I love that! Those growing up in the 1970's and 1980's were more accurate in their reporting. See also the article at the Guardian Unlimited. Wikipedia discusses the derivation of gazumping, which is most commonly used in real estate agreements, where a party backs out of a tentative deal to take a better one. The Yiddish word that may be the root is gazumph which means to swindle or overcharge.
