Um, I've seen this before and I wanted to set it straight.
Polyamory is not ALWAYS just between three individuals. Being polyamorous means you have the ability to be romantically or sexually attracted and be in a relationship with more than one person. And a polyamorous relationship is just that, a relationship with more than one person, whether or not it's one person being with multiple people, everyone liking each other, or anything like that. It's different for everyone. But also, real poly relationships are ALWAYS consentual.
