flip one's lid, to

To lose one’s temper, or to become very excited. An American slang expression dating from the twentieth century, it implies the metaphor of a pot boiling over and pushing off its cover. It appeared in 1951 in the New York Times Book Review: “The funniest book of the lot is enough to make a reader ‘flip’ or ‘flip his lid.’” The closely related flip one’s wig needs no explanation.
