A conniption is a burst of very angry, upset behaviour — the kind where someone makes a scene. In American English people usually say have a conniption or throw a conniption fit. It is informal, a bit old-fashioned, and often half-joking: you say it when someone will be furious, not when you are writing a serious report about real rage. It showed up in American English in the 1830s. It is not a medical word, and it is not common in British everyday talk. Younger speakers may know it from family, from books, or from a parent saying “Don’t have a conniption.” The feeling is closer to a than to quiet, cold anger.
（美式口語）大發脾氣、氣炸
組成It does not split into pieces you can still hear. American English, from the 1830s; the true origin is not known. It may have been a playful twist on an older word such as corruption, or it may be tied to captious, but those are only guesses.
