What is coma mierda?

Literally, eat shit. Often used when referring to the first episode of the television series "Narcos."

Pablo Escobar walks into the police station, frustrated that one of the police officers didn't hold to his deal (he had previously bribed the officer). When the officer says that they need to renegotiate, Pablo says, "Coma mierda. Coma. Mierda."
