My interpretation was that there was no value judgement being made and that this could be equally well articulated using any rhyming words that could indicate a romantic coupling (I've also heard 'chicks before dicks'). That was how I thought about it, but I don't get to choose who feels offended or marginalised by my usage.
Thinking about it now though I've also heard 'mates before dates' which I take to be neutral. Is that a safe way to express the pithy sentiment of prioritising your friends?
