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?
