Pat, if I were to make up a phrase for what this phenomenon is, I would say "noun verbification". Only apparenly verbification is a real term and is in use all over. Scary.
In looking up verbification, I came across
this article by Grammar Girl. While the beginning is about whether Taser as a verb should be tased or tasered, etc., it does get more interesting from there. Stay with the article and you'll learn more about the history of verbification and some of its uses that you may not even think twice about today.
If you haven't heard of Grammar Girl, you might want to check it out anyway. She does an excellent job of breaking down grammar into terms the lay person can understand and retain.
