Control freak is a colloquialism that is usually employed to describe a person obsessed with performing tasks in a way that they perceive as correct. A control freak can become distressed when someone causes a deviation in the way that they prefer to perform tasks.[1] Someone who tries to control how other people perform tasks, while having no good reason for interfering, can also be considered a control freak.[2]
This expression was introduced around the 1960s.[3]
