Question

crocodile tears following phrase​

Answer 1

crocodile tears means fake tears.

Answer 2

The allusion is to the ancient notion that crocodiles weep while devouring their prey. Crocodiles do indeed have lachrymal glands and produce tears to lubricate the eyes as humans do. They don't cry with emotion though. Whatever experience they have when devouring prey we can be certain it isn't remorse.
