Can someone please explain to me when the word "class" became an adjective? I ask because it's nearly impossible to absorb even a hour of TV/radio sports analysis without hearing someone describe someone else as a "class guy". When did this become acceptable grammar?
1. In which sports are individuals most commonly described as "class guys"?
2. Have you ever heard said use of "class" outside of a sports-related context?
3. Who invented the "class guy"?
