Out of practice is a term used to describe someone who has not been doing something for a while and is no longer proficient in it. This term can be described by two words, RUSTY and STALE, which both have five letters. RUSTY implies that the person has not been doing something for a while and is now out of date or not up to speed with the current trends. STALE implies that the person has not been doing something for a long time and is no longer fresh or new.
