twixter
n.— «Meet the Twixters: Twixters not kids anymore, but they’re not adults either. Everybody knows a few of them—full-grown men and women who still live with their parents, who dress and talk and party as they did in their teens, hopping from job to job and date to date, having fun but seemingly going nowhere. Ten years ago, we might have called them Generation X, or slackers, but those temporary labels don’t quite fit anymore.» —“Meet the Twixters” Time (U.S.) Jan. 16, 2005.
