A term used for being
offensive, insulting them by calling them a fruit cake in a
rude way whilst arguing.
It can also be used as a very nice term, by slowly calling the love of your life a fruit cake, you could
start to win them over. They are both as sweet as each other.
Shut up! You
don't know
nothing about this!
Why
don't you shut up you fruit cake!
Aww, my fruit cake, how are you feeling?
