From the Wiki ....
"Gay is a term that primarily refers to a homosexual person or the trait of being homosexual. The term originally meant 'carefree', 'cheerful', or 'bright and showy'.[1]
In the 1960s, gay became the word favored by homosexual men to describe their sexual orientation.[3] By the end of the 20th century and beginning of the 21st century, the word gay was recommended by major LGBT groups and style guides to describe people attracted to members of the same sex,[4][5] although it is more commonly used to refer specifically to men.[6]
