A poly group (also known as a polycule) is a network of polyamorous people’s relationships. Polyamory, in case you’re unaware, is the practice of having multiple romantic or sexual partners at the same time, in contrast to monogamy.

If you were polyamorous and wanted to graph out your relationships, you could do it a few different ways. For example:

• Just you and your partners. If any of your partners are also in relationships with each other, you’d draw lines between them as well.

• Extend an extra level and include all of your partners’ partners (known as metamours), again connecting any pair on the graph who are partners.

• Extend that further and include all of your partners’ partners’ partners (no specific term for this as far as I know). This would likely include people you don’t personally know, and it would be difficult to build a complete graph of all their relationships.

Etc.
