To suddenly go crazy or become angry. Origin was based on the observation that water boiling in a pot could bubble so violently as to "flip the lid" off the pot, leading to the analogy of a human becoming so angry as to "flip their lid". It was later generalized to mean any sudden change in emotional state.
Dude, all I did was show you the latest financial report, no need to flip your lid and start screaming at me!
