Lack of decorum; impropriety of behavior; that in behavior or manners which violates the established rules of civility, custom, or etiquette; indecorousness.
Syn. – Indecorum is sometimes synonymous with indecency; but indecency, more frequently than indecorum, is applied to words or actions which refer to what nature and propriety require to be concealed or suppressed.
