I don't call any objects or people "gay". I don't even use the word, because of the associated meaning the word has come to mean😞.
The uses of the word gay have varied so much over the years, I avoid it because it no longer associates with a clear specific definition.
I've yet to find an inanimate object that is either homosexual or happy ... So "No".
No, I do not. Maybe because I am gay, so I find using it as an insult to be childish.
I had an aloe vera plant and I names it "Gay." I loved that plant. I use to talk to Gay all of the time. It was my favorite plant and I managed to keep it alive for many years.
