Someone who thrives on the idea of envisioning their identity as culturally fluid in terms of their ability to relate to their knowledge of other ways of life; not limited to their ability to speak another language but also in reference to their attraction to more than one gender.
That 20-something anthropology major is really hot and interesting, but she's probably a bilingual bisexual. I'd have better luck with an actual lesbian; one that doesn't leave the country every 6 months to study the feminist implications of the Venus figurine as depicted in the Mayan sculpture of the precolombian era.

A bisexual who believes that labels such as pansexual, polysexual and omnisexual are unnecessary, as they believe that these sexualities are all just bisexual worded differently. BaB's also believe that pansexuality is biphobic and transphobic. To back this up, they cite something called the Bisexual Manifesto, which is a piece of text that's over 33 years old, and defines bisexuality as "Attraction to two or more genders." This definition is vital to BaB's, as it's one of the reasons why they believe that the aforementioned labels are unneeded.
