A license fail occurs when someone taking what should be their first driving practical test prepares thoroughly with expensive lessons, has been waiting for months, is supremely confident of their ability to pass, and has even discussed getting insured for their parent's car upon passing...
...Only to discover that, in the test center waiting room, they have the wrong side of their paper provisional license, meaning they cannot be tested, waste the money spent on taking the test, disappoint family and friends and have to wait 3 months for the next available test.
Also known as "pulling a Charlie".

To fail at something you prepared for, and you can never get it right. Or, simply to fail at anything and everything.
