I have heard it prior to it becoming the gay spouse word. It was used for couples who had been together for a long time, typically live together, but weren't married. I used to work for a man who lived this way. They sometimes referred to it as a partnership. They were successful, hard-working decent people, and raised an exceptionally smart child. The partnership was because she had been in a previous marriage and the ex-hubby was a real piece of work - and that's me being polite about a guy who deserved whatever form of justice he could get. Because of her experience with ex-hubby terrible bastard, she wouldn't marry again, but had everything else with her new guy. It was certainly understandable.

But that's very different from the GenZ's saying that today because they've been so inculcated in the Alphabet mafia's rhetoric, they can't distinguish between hetero terms and terms for the other.

Yeah, whenever I hear that, I'm like, hm.. I didn't know so and so was queer. Another set of buzz words with the younger generations are, I want to be/you want to be/should be the best version of yourself/myself. The "best version of myself", can't tell you how many people on TV say those words. I've heard it so often that I know it must be taught across the country in schools and maybe even the world. It's fine to strive to be the best you can but there's just something weird as I keep hearing it.
