Your stomach's veto power, exercised without consulting you first.

means To forcibly expel the contents of your stomach through your mouth — vomit, in blunter clothing.

from Puke is of uncertain origin, first showing up in English in the 1500s — most famously in Shakespeare's 'As You Like It,' where the infant 'mewling and puking in the nurse's arms' gets immortalized. Some etymologists suspect it's imitative, built to sound like the act itself (that short, ugly 'puke' practically performs the gag), possibly with cousins in German or Dutch dialect words for similar bodily eruptions. But no one can trace it back further with real confidence — it just surfaces, fully formed and unpleasant, exactly like the thing it names.
