Thread:Comments:Australian teacher drops 'gay' from kookaburra folk song/Gay is just a word/reply (4)

That usage of the word is derived—if my memory serves me correctly—from the common derision for homosexuals. Besides, I am sure homosexuals will be offended by the use of the word "gay" to mean "bad", in the same way a woman would be offended if "female" were used to refer to something as despicable.
