It's not a very good umbrella term, the term itself implies a relationship structure where an individual is in multiple, involved intimate relationships. A couple in an open relationship where one or both partners engage in dalliances doesn't fall under that umbrella.

It's posible to draw such clear line? Surely, it's rather easy to convince oneself you have all your relationships nicely compartmentalized..till reality does otherwise.
