We're trying to translate something from the Polish language into English that describes a bad mother. Is there an equivalent phrase to "Deadbeat Dad" except for mothers? Whenever I see "Deadbeat" in front of something, it's usually Dad.
How would you describe a bad mom using a different idiom or phrase?
Edit 1: One additional piece of information: the translation from Polish translates into "villainous mother". There is an element of horribleness that is described in Polish.
