What does defecated mean?
"Defecated" is the past tense and past participle of "defecate," a formal verb meaning to discharge waste matter from the bowels. It belongs chiefly to clinical, medical, and scientific registers: doctors ask patients when they last defecated, veterinarians note whether an animal has defecated normally, and researchers record such observations in technical prose. In everyday speech, English speakers overwhelmingly prefer euphemisms — "went to the bathroom," "did a number two" — which makes "defecated" sound precise but somewhat stark outside professional contexts. The word derives from Latin defaecare, meaning to purify by straining out dregs, sharing its root with "fecal" and "feces." It carries no obscenity or slang connotation, but its bluntness can startle readers accustomed to softer phrasing, so writers typically reserve it for situations where clarity matters more than delicacy.

Etymology of defecated
"Defecated" comes from Latin defaecare, formed from de- ("away, off") and faex/faeces ("dregs, sediment"), so the original sense was to purify or clarify by removing impurities — as one clarifies wine or liquid. The word entered English in the early modern period, initially carrying this figurative sense of purification, before narrowing to its now-dominant physiological meaning of voiding the bowels, since excretion was understood as the body clearing its own dregs. It shares its Latin root with "feces" and "fecal."
