To get wicked mad pissed like a crazy guy on steroids who just stubbed his toe.
Crazy Guy On Steroids: "MUDDA FUCKAAAAAGH, MY TOOOOOOOOOEEEE"
Crazy Guy On Steroids Mom: "Honey, don't have a coniption. Mumsy made you some cookies with extra protien like you like."
Crazy Guy On Steriods On Ground Holding His Foot: "OWWWWWWWWWWWW"
A sad misspelling of those who attempt to use elaborate language, but miserably fail. The correct spelling for the English term is 'conniption', which is defined as a fit of rage, hysteria, panic or alarm.
