Similar to the expression “
in your dreams” which is a sarcastic way of responding to - or interrupting – someone who is busy telling you about their
master plan and all the unrealistically fantastic things they think will happen to them. The difference is in this version you are making it clear they should
get over themselves
Steve: I’m going to win this race and
humiliate you in the process
Harry:
Quit dreaming! That’ll never happen.
