- Having a tongue like a cow, smooth one way and rough the other; and hence, one who gives fair or foul language as may suit his purpose.
- Descriptor for one who speaks eloquently one moment, then swears like a sailor the next, depending on the mood or situation.
~Thomas Wright's 'Dictionary of Obsolete and Provincial English,' 1857
Used in a sentence:
“Our duplicitous manager is such a cow-tongued jerk; he’s polite and servile when he’s talking to corporate, then lambastes us like an apoplectic varlet afterwards.”
