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?
