Short for woman mirage. It is the illusion that you think that a woman/girl is good looking from a distance but becomes disappointingly inaccurate when you get up close.

Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
