I was a film minor in school and in one of my classes we were told the first time "gay" was used to mean homosexual in a movie was Bringing up Baby, with Katherine Hepburn. Thus being a landmark for those who track meanings and connotations.

While new definitions have to be accepted I think it's sad that the old meaning seems to have lost validity, and fine examples of it's old use ridculed and snickered at as in Father Steve's example.
