Finkin, is the uneducated Australian slang term for "Thinking". Anyone who has been to school should know how to pronounce this word properly or any word begining with the letters t and h. Nine out of every ten people in most parts of Western Sydney use this brain dead pronunciation and other forms of neanderthal communication.
