Unicorn

Colloquial; Synonym for hot bi babe or HBB, often derogatory, condescending, or ironic. A bisexual person, usually though not always female, who is willing to join an existing couple, often with the presumption that this person will date and become sexually involved with both members of that couple, and not demand anything or do anything which might cause problems or inconvenience to that couple.

The term is often used to be dismissive of a couple seen to be only superficially polyamorous. Because of the demands that this type of couple places on the woman (that she be single and not take on any additional partners, and become involved with both members of the couple equally, and often "complete" their family as a surrogate mother and housekeeper and/or breadwinner and not do anything that may threaten or disrupt the existing couple), many in the poly community call this type of woman a "unicorn", as in mythical and not likely to be found, even though there are plenty of bipoly women around.

Sometimes the unicorn is expected to not develop any emotional attachment and is strictly there for a sexual relationship (equally distributed to both members of the dyad) and/or is prescripted as a secondary. This term is used as a reminder that bipoly women are people with their own desires, needs, and pre-existing lives, and not fantasy figures or pets. See related prescriptive vs. descriptive.
John wants a single, attractive woman who will love and have sex equally with him and his wife, but not interfere with their marriage, move in together, help raise their kids but not have any of her own, and not have any other partners. He's looking for something that doesn't exist - he's looking for a unicorn!

Prescripted

Adj.

Prescripted comes from Prescribe: Latin, praescribere =

1. to write at the beginning, dictate, order;

2. to lay down a rule : DICTATE;

3. to lay down as a guide, direction, or rule of action : ORDAIN;

4. to specify with authority.

To prescript a relationship, then, is to create a set of rules governing the relationship before the people involved ever get into said relationship. These rules are often set up to define a relationship involving someone who is not even in existence yet and therefore cannot give his or her input into the relationship agreements, such as a married couple deciding the rules for a future extramarital partner before even finding one.

By contrast, a descriptive relationship describes the relationship as it is at the time with input from all involved.
Even though John and Mary haven't met anyone they're interested in yet, they have decided beforehand that anyone they date will be female, in love with them both equally, single, will live no more than 10 miles away, will not call John by the nickname "bunnylips", will not eat with them at their favorite restaurant, and cannot ever listen to the song John and Mary danced to at their wedding while John and/or Mary are in the room with her. When they meet her, these rules are non-negotiable and she has no say in them. They prescripted their relationship.
