The phrasal verb "cry off" is typically used in informal speech, with less frequency in formal contexts. It means to decide not to fulfill an agreement or plan, often at the last minute, typically due to unforeseen circumstances or a change of mind. The verb "cry" in this context suggests a kind of withdrawal or renunciation. Usage often appears in British English more than American English and might be used in contexts such as social arrangements or casual commitments. An example would be, "She decided to cry off from attending the concert due to a sudden headache." It implies a degree of personal regret or reluctance, as the promise or initial acceptance is typically withdrawn for a purpose that's somewhat unexpected.
