Doing anything but that which you are supposed to be doing during a specific time frame.
E.G Pretending to do something for which you are being payed for, such as a your job, but instead doing other things (like having a laugh, phoning your friends, hiding from your boss, surfing the internet, playing computer games, having a sly cigarette) that are totally unrelated or unconected to that which is within your job description.
Taking 2 hours for lunch instead of 1 and getting a collegue to cover for you.
Leaving work earlier than you should, and hoping your boss doesn't notice.
Calling in sick to work, then going out for an all day pub crawl.
