To be gay is absolutely completely 100% fine. But it's also, like, really gay. Does that help?

I think they were just making a joke because git.gay.

As in, not as bad or weird but more making fun of the homophobic "it's gay" argument that used to be used.

I do the same thing with my spousy occasionally. We're gay as hell, so it's funny as shit when I stroll by their room and just say, "Gaaaaaaaay~". Lol.
