The word 'rusty' is used to describe someone or something that has not been used or practiced for a long time and as a result, their skills or abilities have become slightly weakened. For example, if someone says "I'm feeling a bit rusty on my guitar playing," it means they haven't played the guitar for a long time and might not be as good as they used to be. Generally, the word 'rusty' is used in a casual or conversational context to describe a person's skill or ability level.
