This is just a funny word, said aloud by a friend today near the Little Red Lighthouse.
It reminded me of another friend calling people who'd been together in what struck me as an excellent many-years-long relationship "coupled out".
Years ago I went out with a man who made it very clear that I was never to call him my "partner in crime." It would never have occurred to me to use that expression.
Another boyfriend was very particular about whether we were going out, seeing each other, dating, or involved.
I don't know if I like the idea of being in a serious relationship with a man who's relationshippy (the silliness of the word says it all), but coupling out seems all right.
