makeinu
n.— «Single and childless women in their 30s or older are makeinu, According to novelist Junko Sakai, who coined the phrase with her bestseller “Makeinu no Toboe (The Howl of the Losing Dog),” It doesn’t matter how successful, beautiful or happy they might be. They’re all “loser dogs.”…Loser dogs are a social underclass from the way they act. Without a family to care for, or a husband to order them about, they enjoy sizable disposable incomes and lots of free time.» —“Single and Winner” by Dion Ringo Pensil Patah (Indonesia) Apr. 19, 2004.
