In the first half of the 20th century, the word “gay” was synonymous with “happy” or “joyous.” Now it refers to homosexuality. How did such a formerly innocent, innocuous term come to be associated with something as unsavory and unsanitary as queer buttsex?

As can be readily seen, use of the word “gay” as a euphemism for homosexuality is yet another instance of the jewing of the English language.
