So what I'm trying to do is set up two characters to make a habit of speaking in cliches to each other. Just sort of their form of witty banter. Unfortunately, I'm a little low on wit. Is there a dictionary of popular colloquialisms that I could use? Preferably online. That's the general request.
In case I don't get an answer to the general request, and to give you a clearer idea of what I'm looking for, here's the specific request...would any of you be able to help me find ways to express the idea of leaving a party early. So far I've got:
Always leave 'em wanting more;
Love 'em and leave 'em;
Exit on a high note;
Go out on top.
But it really seems like there should be more. Any help would be appreciated.
