Nobody, which is why poly is exclusively for people with a scheduling kink.
But yeah, I’ve never met a poly person who would bring three of their partners to a single event and introduce them all as their girlfriends. In fact, I don’t think I’ve ever met a poly who calls their partners “girlfriend”.
I was in a poly relationship. I called my girlfriend “girlfriend” and she called me her “boyfriend,” and she also called her other boyfriend “boyfriend” and he called her “girlfriend.”
It was a great, genuinely healthy relationship, and Kyle was an excellent dude who always treated our girlfriend excellently
I’ve allowed my partner to refer to me as girlfriend to make discussion with others easier. I don’t love it, it doesn’t sound like a longterm adult relationship, but I recognize it’s easier to say “my wife and my girlfriend”.
and both of us go to family Christmas, though not everyone needs to know relationship status.
… you’re absolutely right about the scheduling thing though.
