The feminine version of 'son of a bitch', althoughbear in mind that a 'daughter of a bitch' is just another bitch.
From The Familiar of Zero:
Louise Valliere (Tearing up): Don't lie to me... when you were the one who called the maid. You prefer her, don't you?
Saito Hiraga (Shouting angrily): Are you a fucking idiot?! Why would I willingly please a selfish girl like you, you fucking goddamn daughter of a bitch cunt?!
Someone so disgusting and twisted for various reasons, such as weird fetishes, disturbing behaviour, personality related reasons or to do an act so gross, that you are not just a son of a bitch, but a sick son of a bitch
