Cultural Obscurity

There are certain phrases and terms that we use as a culture that are universally understood in our time and place. Yet some terms pass into the twilight of our conscieness. We've all heard senior citizens and old movies use terms like "the cats meow," and "23 skidoo." Nobody uses those now. Which brings me to this point, are we watching the term "Chicken" as conoting someone who is timid and afraid, move into obscurity before our eyes? Who calls someone chicken anymore. Marty McFly used it, but that was 1985. Lets all have a moment of silence for chicken, and hope "don't go there" follows it to a miserable death.
