used to tell someone that you cannot accept an invitation now, but would like to do so at a later time: Mind if I take a rain check on that drink? I have to work late tonight.

Should we take a rain check?

To refuse an offer or invitation but with the hope or promise that it can be postponed to a later date or time.

Can we rain check meaning?

: a ticket given to people so that they can go to another event (such as a baseball game) if the one they were watching or planning to go to is canceled or stopped because of rain. : a promise to allow someone to buy or do something in the future because it is not possible to buy or do it now.
