the moment water decides it's done being polite and starts pressing charges

means So hot it burns on contact — usually said of liquids or steam, and by extension of harsh, stinging criticism.

from From Old French 'escalder,' to burn with hot liquid, which traces back to Late Latin 'excaldare' — from 'ex-' (thoroughly) plus 'calidus' (hot), the same 'calidus' that simmers behind words like 'cauldron' and 'calorie.' So at its root, scalding is being thoroughly heated, water doing exactly what fire taught it.
