What is Fujoshi?
1.
Jap. 腐女子. literally: rotten girl. A pun, based on the homonymous term for woman (jap. 婦女子). Ironical self-description by readers of Yaoi Dōjinshi. The female counterpart to the male Otaku.
(translated from the german wikipedia page for Otaku)
I'm a fujoshi.
(The rulesets demand me to write shit even though I don't know what I'm talking about, and at the same time prevents me to link an image that'll explain things better than a thousand words)
2.
Homophile women who get aroused by imagining two (or more) cute guys loving each other.
Fujoshi herself is not included in the imagination, usually those cute guys are not gay, and the situation is absolutely impossible.
Yoko is such a Fujoshi!
She masterbates to Supernatural imagining Sam and Dean in bed, naked, touching each other!!!
