put up your feet and stay awhile

If someone asks you to put your feet up and relax awhile, they are trying to be polite and ask you to kick back and relax. This phrase has become a cliche because of how often it is used in this exact wording or a slight variation to it. When someone tells you that you should put your feet up and relax awhile, they are speaking literally that you should relax in their home or in yours, usually after some type of hard work is completed.
