Breaking out suddenly and violently, like a volcano releasing lava, or emotions breaking forth uncontrollably.
From Latin 'erumpere' meaning to burst forth, from 'e-' (out) plus 'rumpere' (to break). Originally geological, extended to describe any sudden violent emergence by the 1600s.
The word perfectly captures the similarity between volcanic explosions and emotional outbursts - both involve tremendous pressure building up underground until it can no longer be contained. We instinctively understand that anger 'erupts' because we feel the same build-up and release.
