The idiom "slip someone's mind" refers to forgetting something unintentionally. It is commonly used when someone neglects to recall a specific detail or task without meaning to. The phrase can describe a temporary lapse in memory or when someone fails to remember something. The origin of this idiom is based on the idea that thoughts or memories can slip away from someone's mind just like objects slipping through one's fingers. The use of the word "slip" implies a sudden and unexpected act of forgetting.
