The quality or state of being arrant; complete and utter outrageousness or shamelessness.
From 'arrant' (from Middle English via Old French 'errant,' meaning wandering or straying from truth) plus the suffix '-ness' (forming abstract nouns). 'Arrant' originally meant deviating from proper behavior.
The word 'arrant' has this cool hidden history—it started as 'errant' (like errant knights who wander), then shifted to mean someone who wanders from truth and honesty, then became our modern 'complete and utter badness.'
