What’s up with this? “son of a bitch” is common as hell but there’s no female equivalency? This is madness! I refuse to believe women are immune from having bitch mothers.
same goes for the “son of a whore” equivalent and “son of a gun”. I’ve heard women say “well, she’s a son of a bitch”. Not good enough IMHO.
At least motherfucker is ambiguous and it can be used liberally for both sexes.
