HOMOSEXUAL, because there’s nothing GAY about it.
Actually, “gay” is a lot more descriptive than you might think. If you look up the dictionary definition (Merriam-Webster), one of the definitions of “gay” is “licentious.” “Licentious” means “lacking legal or moral restraints; especially : disregarding sexual restraints.” That dictionary definition describes them pretty accurately.
They use “gay” as a double entendre, so people misunderstand and think they mean the usual definition of “happy and excited; cheerful and lively.” They’re none of those things.
