A strange girl, usually greek, hermaphroditic, and into Final Fantasy. Normally, it is a fan of FFVII's Cloud x Tifa character pairing. We USUALLY call this kind of fan a Clito, but because of the extremity of this fandom, we call it a Tana. Tana's are virgins for their whole lives.
"Don't talk to that girl, Tom, she's a Tana."
