Queer
From Tardis Wiki, the free Doctor Who reference
Queer was a human epithet for a homosexual. Clement McDonald once called Ianto Jones a queer, saying that he "could smell it". Ianto objected, implying through the phrase, "This isn't 1965" that the word was old-fashioned and no longer appropriate in the 21st century. (TW: Children of Earth: Day Three)
