Partner Systems is a term to describe two or more systems that are in an intimate relationship. This could be romantic, plationic, queerplatonic, sexual, sensual, a passionate friendship, or any other type or relationship. Not every headmate in the system has to be involved, so long as two or more in each system are involved, they can be classified under this term.
This is not the same as headmates who are involved within their own system, as that falls under System-Partnership. However, the two terms can overlap if one is dating people in their own system as well as dating people in other systems.
