: There are only heterosexual and homosexual people, no bisexuals.
- Straight: There are no bisexual people in the world.
- Exaggerated: Bisexuality is an absolute taboo in the setting and mentioning is payable on death.
- There are no bisexual people in the city, but they exist in other places.
- But Not Too Bi
- All of the characters are genderless/monogender aliens.
- There are probably bisexual characters, but due to living in a biphobic universe, they are forced to hide their sexualities.
- Subverted: One person is bisexual...
- Double Subverted: ...but later finds out that they are straight...
- Parodied: Every bisexual person on Earth was shoved onto a spaceship and sent to the Moon.
- Zig Zagged: ...but another person turns out to be bisexual instead.
- Averted: There are bisexual people.
- The writers don't believe that bisexual people exist in real life.
- The programmers feel that programming bisexual behavior for characters is too complicated, so they just stick to heterosexual and homosexual characters.
- The audience doesn't believe that bisexual people exist in real life; so, developers are forced to compel according to their perception.
- Lampshaded: "Isn't it weird that no one ever likes guys and gals?"
- Invoked: The villain exclusively targets bisexual people.
- Exploited: ???
- Defied: "What? Are you just insinuating I'm straight just because I so happen to be a man dating a woman at the moment? That's ignorant and stupid."

- Conversed: ???
- Deconstructed: The lack of bisexual people spawns an investigation by the police.
- Reconstructed: The Bisexual Rights movement occurred calling out both heterosexuals and homosexuals alike on how hypocritical the latter is being and how the former is denying that bisexuality exists.
- Implied: "She had a boyfriend at one point, but later I guess she must have discovered she was gay."
- Played For Laughs: One night at a campfire, the characters tell them about the ancient legend of the bisexuals who are rumored to exist on this very planet...But they dismiss it as nonsense.
- Played For Drama: Because bisexuality is considered even more taboo than homosexuality, the bisexuals of the setting have to keep their sexuality a secret or to swear it off altogether, which leads to many of them growing frustrated and miserable.
You can look into the main page if you want, but I guarantee you this: No Bisexuals
