the.com/fume

means To be intensely angry while staying outwardly silent or sealed-up about it — the slow-burn rage that shows in your face, not your mouth.

from From Latin 'fumus,' meaning smoke — the same root that gives us 'fumigate' and 'perfume.' The word first described actual smoke or vapor rising off something, and by the 1500s English speakers had stretched it metaphorically: a furious person seemed to be smoldering, giving off heat and vapor like something slowly catching fire. The anger sense simply rode in on the image of smoke with nowhere to go.
