Two overused and denatured substitutes that I would like to see consigned to the proverbial dust-bin (we in the USA would say "trashcan")of history are "awesome" (a once valuable descriptor of such things as a waterfall, a volcanic eruption, the power of a storm, but now generally used by pre-teenagers to describe a video or a pair of shoes) and "cool" (in its latter day and debsaed form, generally pronounce almost like "cawl" and frequently used to describe accumulated or desired consumer goods, rather than the jazz musician mystique it once had).
