The phrasal verb "cock up" is predominantly used in informal speech, with a rather casual and sometimes slightly vulgar tone. It means to make a mistake or do something badly, often as a result of incompetence or negligence. This term is most commonly found in British English and is not typically used in formal writing or professional contexts. It is a versatile verb that is often used when errors or mishaps occur, particularly in situations involving tasks, plans, or projects. Such usage indicates a level of humor or frustration about the error. Despite its informal nature, the expression can be applied across various scenarios ranging from personal to professional settings, although it maintains a degree of levity that is not suited for serious or official discourse.
