A lifestyle of non-monogany where sexual relations occur outside the established couple. Swingers tend to refrain from romantic attachments with their outside partners, thus differentiating themselves from PolyAmorists. There is some overlap between the two communities, though the closeness of the comparisons are generally not acknowledged.
Swingers often engage in the activity as a couple. "Swing Parties" are venues where the activity may occur.
