Always-leaving-never-leaver 

Someone who is constantly telling their friends, family and employers that they are leaving the country, but they never do. They may also throw pointless "leaving parties" - Very frustrating when they are still there 3 months later! This term coined by popular New Zealand DJs Fletch and Vaughan

Sally is an always-leaving-never-leaver as she has handed in her resignation 3 times and is constantly telling her workmates that she is moving overseas, however she never does.
