A woman who isn't really a Lesbian but is just acting gay, either as a response to negative learned behavior towards men or not wanting to be alone due to unattractiveness.
A)Becky dumped Cindy when she finally met a guy who didn't make her feel threatened by men. I guess she was only a Thesbian after all. B) Tina will not drop her Thesbian identity because she would be lonely but would consider doing so if the right man came along. C) Sharon prefers men but her heavy-set build and man-ish looks leaves Thesbianism her only option to human companionship.
