when someone fails repeatedly and miserably he/she is said to be a liaf.
John is such a liaf. He has failed his drivers test 4 times!

Someone who fails miserably. An epic failure. Someone who is oblivious to the fact that the word Liaf means FAIL backwards. Someone who cannot win. A hopeless person.
