the japanese are 'turning japanese'

"A few years ago, Tokyo Gakugei University sociologist Masahiro Yamada coined the phrase ''parasite singles'' to describe young people who sponge off their parents and use their rent-free incomes to splurge on designer goodies, expensive dinners and trips abroad. It came from the 1997 Japanese horror movie Parasite Eve and applies to young, live-at-home men and women alike, though Yamada says the most carefree of the parasite singles tend to be women; the men are more serious about establishing careers and moving out on their own one day.
The phrase caught on. Some single women even printed up business cards defiantly describing themselves as 'parasite singles.'"
