Extremely angry, raging, or furious; in a state of wild fury or passion.
From Latin 'furibundus' (raging, maddened), from 'furere' (to rage) + suffix '-bundus' (full of). This archaic English term is rarely used in modern speech.
This word captures an intensity that 'angry' can't touch—it means you're so furious you're practically frothing at the mouth. Shakespeare never used it, but if he'd known the word, he would have given it to Lear.
