a four-faucet biological keg the cow refills daily whether you ask or not

means The baggy, gland-filled organ hanging beneath a cow (or goat, sheep, etc.) that produces and dispenses milk through its teats.

from An old Germanic word, traceable to Old English 'uder,' and a close cousin of Dutch 'uier' and German 'Euter.' Push back further and it links to the same ancient root that gave Latin 'uber' (udder, also 'fertile, abundant') and Greek 'outhar' — all reaching toward a shared Proto-Indo-European ancestor for the milk-bearing organ. So the word is genuinely as old as people keeping milk-giving animals.
