Have you ever wondered what is a unicorn in dating? Typically, a unicorn is an individual who is in a romantic or sexual relationship with an already existing couple. This is usually a consensually non-monogamous relationship arrangement. The term is traditionally used for a bisexual/queer woman who dates a straight couple, but it is now used more broadly in today’s world.
The "unicorn" is a moniker based on the notion that it can seem hard to find someone who is attracted to both partners, desires a compatible relationship with both, and is willing to accept the couple's existing boundaries. But there is a big difference, a unicorn is a person, not a relationship setup. The relationship is between the couple, the third partner and the agreements they have.
Let’s understand what is a unicorn in dating:
Unicorn: A person dating or having an intimate relationship with an established couple.
Traditional meaning: Usually a bisexual or queer woman dating a heterosexual couple.
Relationship: Unicorn relationship is usually connected to CNM (consensual non-monogamy).
Connection: It might be sexual, romantic, or both kinds.
Key difference: Everybody involved should consent voluntarily.
In the context of dating, unicorn is usually used to describe a third person who is willing to join a couple for a romantic or sexual relationship or both. Traditional usage of the term usually involves the case when a bisexual woman dates a couple. But there are no such strict requirements for gender and sexuality. The modern understanding of the term involves cases where someone wants to date couples.
Such a union falls under the umbrella of consensual non-monogamy (CNM). CNM is a set of multiple relationships between people where everybody consents to romantic, sexual, or other intimate relationships outside of the traditional monogamy. The study defines CNM precisely from infidelity due to the involvement of consent in the agreement.
“Unicorning” is a slang used to describe the process of becoming involved with a couple as a “unicorn”. For instance, a unicorn making a profile and actively searching for a couple to date them. This falls under the category of unicorning. Though this is still an informal term, not an established one, so it can be interpreted differently at different times. For example, according to the urban dictionary, unicorning takes a whole different meaning.
There’s a minor difference between unicorn hunting and unicorning, even though they are closely related. “Unicorn hunting” is when a couple approaches the third person as someone who must fit predetermined rules rather than as an equal participant. While “unicorning” is simply being that third person. But unicorn hunting often carries more criticism, particularly when the third person’s needs are neglected or treated as secondary.
The name is derived from the idea that finding someone who will join an existing couple in a way that works for everyone is as difficult as spotting a mythical unicorn. A mature couple may desire a person who is:

The meaning of a unicorn person is pretty simple: it’s the term used for a person who is willing to enter into a romantic or sexual relationship with an established couple. The person may describe themselves as:
This may vary depending on the person as there is no universal answer. But generally a unicorn person desires:

There's a difference between unicorn dating and unicorn hunting even though both the terms seem similar.
Unicorn Dating | Unicorn Hunting |
|---|---|
Third person dating an existing couple | Couple actively looking for a third person to join them |
Focuses on meeting a compatible person | Focuses on finding someone to fit a couple's expectations |
Allows the relationship to develop naturally | May begin with fixed rules |
Third person's needs are discussed | Couple's needs may dominate |
Emphasis on individual autonomy | The couple may try to hold a greater control |
Relationship structure can evolve | The desired structure is fixed from the beginning |
There are different ways that a unicorn can be involved in relationship arrangements. Let’s think of three possibilities:
All three are romantically or sexually involved with one another. This can look like a triad or throuple if the relationship is arranged as a continuing relationship among three people .
The couple remains in an established relationship, and one or both partners develop a relationship with the third person. The emotional ties can be different for all and this remains consensual.
The third person can have sexual experiences with the couple without wanting a romantic relationship. This is a type of consensual non-monogamy, but it is not a romantic relationship between three people.
Feature | Unicorn arrangement | Throuple |
|---|---|---|
What does it describe? | Usually the third person involving with the couple | A three-person relationship |
Romantic involvement | May or may not exist | Usually central |
Sexual involvement | May be present | May be present |
Commitment | Can range from casual to committed | Often ongoing and committed |
Relationship structure | Vary from person to person | Three people intentionally forming a relationship |
There is no official rule book on how to date unicorns. The "rules" are created by those involved in the relationship. However, there are some guidelines which will help clarify the situation and avoid complications.
This is not just etiquette - it is the definition. The American Psychological Association's Division 44 describes consensual non-monogamy as an umbrella term for relationships in which all partners give explicit consent to romantic, intimate, or sexual involvement with multiple people, and stresses that these are consensual relationships, not infidelity. Applied to a unicorn in relationship terms, "all partners" includes the third person, not only the couple. The unicorn person's meaning breaks down entirely if consent flows in one direction.
Discuss the following:
Three people do not necessarily have the same feelings developing at the same speed. Someone may form emotional bonds faster, while the other one may be interested in a more casual relationship. Pressuring each other into feeling the same thing is not necessary.
The third individual should be able to express their emotions. Consent is not something someone gives once at the beginning. It can change as the relationship develops.
Before sexual activity, partners should openly discuss safer-sex practices, testing, contraception where relevant, and agreements about other partners. These conversations should happen before assumptions are made.
Relationship arrangements can change. A setup that feels comfortable after one month may need adjustment later. Regular check-ins give everyone an opportunity to say what is working and what is not.

Not all challenges necessarily mean a problem. However, some specific signs require further attention.
The Couple Makes All Decisions: When the couple makes all decisions without consulting the third party, there might be an unhealthy relationship.

Understanding the terminology can make these conversations much easier.
Relationship style | Basic meaning |
|---|---|
Monogamy | Two partners agree to romantic relationship without involving any third person |
Open relationship | A couple permits some outside sexual or romantic connections according to agreed boundaries |
Swinging | Couples engage in consensual sexual experiences with other couples |
Polyamory | People openly seek multiple romantic relationships |
Throuple | Three people maintain an equally romantic relationship together |
Unicorn dating | A third person dates or becomes intimate with an established couple |
Couple privilege refers to the advantages an established couple may have compared with a newer or additional partner. For example, the couple may already:
The third partner enters an existing structure rather than starting on completely equal ground. That does not automatically make the relationship unfair. It simply means that everyone should recognize the imbalance and discuss how decisions will be made.
There is no perfect formula to being a successful unicorn in the dating arrangement. It is contingent upon whether all parties are free to take part.
Concentrate on these five principles:
Yes, a man can certainly be in the role traditionally described as a unicorn. Unicorn man or unicorn male are the terms used for a male unicorn who participates as a third person and dates an already existing couple. Involved male can be bisexual or heterosexual. Though the terms like male unicorn are less used and less common.
For example, a man might date:
Historically, the term unicorn has been more strongly associated with bisexual women, which is why terms like “unicorn man” and “male unicorn” can be confusing. But the basic idea of a woman joining an existing couple is not necessarily exclusive to women.
When an established couple considers involving another individual in their relationship, the initial talk needs to be between the couple only.
Are we really interested?
One being convinced by the other because he/she does not want to lose him/her is not the same as both having an enthusiastic interest.
What do we really want?
The various possibilities of casual sex, dating, romance, or even the three-person relationship entail different expectations.
Can we cope with mixed emotions?
How would the couple cope if one became emotionally attached to the other person?
Are we ready for the change?
The addition of another person may bring changes in the relationship as it exists. They need to be ready for the change in communication rather than expecting things to continue being as they were.
Does the third person have the right to dissent?
If the answer is negative, then more discussion needs to take place before proceeding any further.
What matters most in the concept of unicorn dating is not the term itself but the understanding of the underlying arrangement. It is essential to understand what is a unicorn in dating, how to date a unicorn, how it feels like to be with a unicorn in dating and most important unicorn person meaning.
A healthy arrangement is based on consent, communication, boundaries, autonomy, transparency, and respecting the needs of all individuals. A third person should not be seen as the accessory to an existing relationship; he/she is an individual joining the relationship and having his/her own preferences and choices. At the end of the day, dating a unicorn is not about looking for a perfect "third" but deciding for yourself and for your partner whether your relationship works out well for all three of you.
