The only democratic vote in your house, and someone always loses.

means The hinged ring (and lid) fitted to a toilet bowl for sitting on — simple hardware that somehow became the longest-running argument in domestic history.

from The surprising part is the word itself: 'toilet' comes from French 'toilette,' a diminutive of 'toile' meaning 'cloth' — originally the cloth cover on a dressing table, then the whole ritual of washing, dressing, and grooming at one's dressing table. Over the 19th century 'toilet' drifted in English from 'grooming routine' to 'the room where grooming happens' to, euphemistically, the fixture itself. 'Seat' is just old plain English, related to 'sit,' doing exactly what it says. So the up-or-down battlefield is named, etymologically, after a dainty French cloth — a genteel word dragged, over centuries, into much less genteel duty.
