Have you ever flipped your lid?  No doubt you have.  The saying is a uniquely American slang expression.  According to Free Dictionary dot com it means to react to something with strong emotion. The reaction can be to something positive or negative or, used as a joke  to go insane.  It dates from the twentieth century and it implies the metaphor of a pot boiling over and pushing off its cover. It appeared in the 30’s and 40’s and 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.”  Your lid is not the only thing you can flip. You might just flip, flip your lid or even flip your wig.  Listen to the podcast here; https://theriver953.com/lonnies-fun-fact
