Alright this is the way I like to think of the word Gay in its modern usage or at least the way I believe it came to be in use by people:
Alright so gay is a synonym for queer correct? Gay and queer basically mean the same thing
Queer was traditionally used to identify something as strange or unusual, now when people want to say that someting is strange, unbelievable or just plain wierd to them or even stupid they use "GAY"
Voulez THE END OF THE MYSTERY!! agree?
