Hi Jacky: "Darn" by definition, refers to repairing a hole in a piece of clothing. Darn does not apply to repairing things other than clothing. "Darn" has a secondary usage. It is used as a polite substitute for the profanity, "damn". In polite company, "damn" is profanity and "darn" is considered an acceptable epithet. However, usages have changed very much in the past century. In contemporary American, "damn" is itself, a very mild profanity. Darn is mostly out of fashion and a forgotten term. In contemporary America, Profanity has become more acceptable in general usage. There are still however, occasions where the coarser forms of profanity are generally prohibited as a societal norm. .
