Queerplatonic
Queerplatonic is a word for describing relationships where an intense emotional connection transcending what people usually think of as "friendship" is present, but the relationship is not romantic in nature; people in a queerplatonic relationship may think of themselves as partners, may plan on spending their lives together, etc.
The 'queer' is a reference to the idea of "queering" relationships and ideas about relationships, not for describing the orientations or genders of anyone in a queerplatonic relationship. Anyone, sexual or asexual, romantic or aromantic, straight, gay, queer, bi, lesbian, poly, cis, trans, etc etc can be in a queerplatonic relationship, can have more than one such relationship, and there can be more than two people in a queerplatonic relationship; couples, triads, quads, whatever. The key feature is the idea of being deeply connected to someone, without a romantic element (though a queerplatonic relationship can be sexual).
This is more or less the definition of a hypertwin.
