Conniption fit.

The correct spelling is conniption (also conniptions, conniption fit), an angry or hysterical outburst.

The plural of conniption is spelled "conniptions". Conniption is an American and Canadian slang word, meaning a fit of rage, alarm or hysteria. It is rarely, if ever, heard in the rest of the world.

A conniption is a burst of rage or anger. It is also used with the word fit denoting a tantrum.

Mary pitched a conniption fit when she found out her brother broke her Ipod.

The origins of the word conniption, which appeared in usage in the 1830s, are cloudy and several theories have taken root into possible origins of the word:

1) Conniption is a literal corruption of the word 'corruption' which at one time meant feelings of anger or sadness.

2) Conniption is a nonsense word hinting at a mock latin origin.

3) Conniption is of Yiddish origins, such as the word Knish, due to the use of hard Ks and Ns.
