When those lines are blurred, that relationship can be called queerplatonic. They are typically characterized by having a level of emotional closeness and dedication comparable to or equal to that found in a romantic relationship, though the relationship is not romantic in nature. For some a QPR could look like a close friendship, for others it may outwardly appear to more closely resemble a romantic relationship. Queerplatonic relationships may involve some forms of physical affection which are normally considered exclusive to romantic relationships, such as hand-holding, cuddling, kissing, or having sex. Some queerplatonic couples will live together or get (platonically) married. Queerplatonic relationships can look different for everyone, depending on what the people involved are comfortable with.
Queerplatonic relationships are common among a-spec people, however one does not have to identify as a-spec to be in a queerplatonic relationship. One also does not have to be queer to be in a queerplatonic relationship. Pursuing a queerplatonic relationship is not necessarily mutually exclusive with pursuing romantic relationships. A queerplatonic relationship can be monogamous or polyamorous- involving more than two people.
People in queerplatonic relationships might refer to each other as their queerplatonic partner (QPP) or as "zucchini", a term that was originally a joke in the a-spec community about lacking a word to properly describe the term, so they could just use any word they want, like zucchini. A queerplatonic crush is most commonly called a squish (the same a platonic crush), and is less commonly called a plush or a squash.
Queerplatonic attraction is a form of tertiary attraction experienced mainly, but not exclusively, by a-spec people. It is defined as the desire to be in a queerplatonic relationship with someone in particular.
Queerplatonic attraction can be very similar to platonic attraction and alterous attraction. For some people these types of attraction greatly overlap and not all people feel a distinction between them. For others they may feel like there is a clear distinction between these feelings. Among those who do feel a distinction queerplatonic attraction is often much stronger and more intimate than purely platonic attraction. Alterous attraction is the desire for intimacy that is neither platonic or romantic, queerplatonic is considered an extension of platonic.
Someone who does not experience queerplatonic attraction and/or does not desire queerplatonic relationships may call themself aqueerplatonic. Queerplatonic attraction is not a requirement for a QPR. Some aqueerplatonic people may still want or have queerplatonic relationship, they just do not get plushes. Other aqueerplatonic might not desire a queerplatonic relationship. They may also identify as nonamorous.
The first apparent usage of the term queerplatonic was on December 25, 2010 in a thread called Kaz's Scribblings. The term was made out of a desire to describe an aromantic form of relationships, outside the strict categories of romance and friendship.
On Janurary 22, 2011 was posted on Tumblr by Meloukhia, also known as S. E. Smith, where it quickly gained popularity. In May 2014 the term quasiplatonic relationships was coined for aromantics who were uncomfortable with using the term queer.
At least four different flag designs have been proposed for queerplatonic. Most of these flags use the colors yellow and pink. Yellow is commonly used to symbolize platonic relationships. Pink is possibly use because it is a light form of red, which is commonly used to represent romantic attraction, showing that queerplatonic relationships can sometimes resemble romantic relationships but that they are different nonetheless.
