Here's Urban Dictionary's definition: "The condition of a person who takes advantage of being out of a job to have the time of their life. I spent all day Tuesday at the pool; funemployment rocks!"An acquaintance of mine was laid off with a nice severance package and a big bonus for training the foreign programmer who would take over his job when it was moved to India. He took the resultant pot of money and treated himself to a several-months-long cross-country motorcycle trip.
When funds ran low, he came home, filed for unemployment, and eventually found work. He called it a "sabbatical." Perhaps "funemploymemt" is a better descriptor as he did not use the time off to improve work skills. In truth he took a prolonged vacation, what British colonial officials called "long service leave."
