SD — abbreviation of "Sexually Deviant". Intended to replace usage of the word "gay" in someone's vocabulary; specifically when such a person has developed a habit of saying the word "gay" to describe something "bad", though at the same time wants to stop promoting (and thus legitimising) the artificial idea that "gay" means anything else other than a physical sexual fetish for members of the same sex and is therefore no different than any other form of sexual deviancy (fetishes) being completely carnal in nature and illegitimate as an "identity" for a human being or group of human beings. Biblically "sodomite".
