means To break apart suddenly and forcefully, usually from too much pressure building inside — or to erupt abruptly into some action or emotion.

from From Old English 'berstan,' a sturdy Germanic verb meaning to break violently or shatter, with cousins throughout the Germanic languages (like German 'bersten'). It's one of those satisfying words that's barely changed in a thousand years — probably because 'burst' already sounds like what it means.
