the body's nuclear option, evolved to expel poison before poison expels you
means To forcefully eject the contents of your stomach up and out through the mouth, usually because something in there has gone badly wrong.
from From Latin 'vomere,' to spew or discharge, which gave the frequentative 'vomitare' and the noun 'vomitus.' English took it up in the late 1300s. The root runs deep in the Indo-European family, with a probable cousin in Greek 'emein' (to vomit) — the same source that gives us 'emetic,' the medicine that deliberately summons what 'vomit' describes.
