The origin of the term is not clear, but it seems have entered the popular lexicon starting in the early 2010s.[1] By the 2020s, discussions of polycules had entered the mainstream media.[5][6]
Terms
While polycules can take on many different configurations, there are a few common structures and terms.[2]
V structure describes a three-person polycule where one person is dating the two others, but the two others are not dating one another.[2] It is also known as a type of triad.[7]
N structure describes a four-person polycule where each couple contributes one person to a third relationship. It takes its name from the letter "N", since each line represents a relationship, and each end point represents an individual.[2]
Throuple describes a group of three people where all individuals are in a relationship with the other two people in the group.[2][8]
Quad describes a four-person polycule. While N structures are all quads, not all quads are N structures.[7][2]
Metamour is a term that refers to one's partner's partner.[2]
In popular culture
The television program Riverdale series finale revealed a four-person polycule, or quad, between Archie, Betty, Veronica and Jughead.[9]
Luca Guadagnino's 2024 movie Challengers drew social media references to the three characters of Tashi, Patrick and Art as a "throuple".[11] However, members of the polyamorous community pushed back on using the "throuple" term since the relationship dynamics didn't follow the conventions of ethical non-monogamy and transparency.[11]
