The passing of pop references

One of my ongoing passions is pondering the passing of pop culture references. Baby boomers have lived through decades of new hip phrases -- for instance, the hip word for "good" has evolved every few years, from "cool" to "groovy" to "far out" (thanks to John Denver for killing that one off by using it too much) to "excellent" to "bad" to "tight" to other words and phrases.Young people are constantly introducing new words and bringing new meanings to old words. That's a part of the evolution of culture and language.
