Somebody who feels themselves to be out of their profundity thus befuddled or idiotic like a sheep; maybe following the terrible case of others. Sheep were and are world-renowned for getting themselves lost or into potential harm. “I have gone astray like a lost sheep; seek thy servant; for I do not forget thy commandments.” Psalm 119:176 KJV see also Jeremiah 50:6; Matthew 10:5-6
