The phrase 'crocodile tears' means showing insincere remorse. It comes from the ancient belief that crocodiles weep while devouring their prey to show sadness. The truth? Crocodiles *do* produce tears while eating, but not out of emotion. When they open their jaws wide or hiss while feeding, air is forced through their sinuses, stimulating their lacrimal glands to empty fluid into the eye. It is purely a biological reflex to keep their eyes lubricated, not a sign of guilt.
