It's a more vulgar version of "https://fr.m.wiktionary.org/wiki/s%E2%80%99en_brosser_le_nom...".
However, I found it quite surprising to add such a rare thing but not the most usual things like "I've got nothing to wax" and its vulgar form.
German "das ist mir Wurst" is also a lot weaker than "zero fucks given", at least use something stronger like "das interessiert keinen Arsch" (no asshole cares). Also "zero fucks given" in the sense of "irresponsible, he just does it and doesn't care who gets hurt" doesn't really have an equivalent idiom. Maybe "als druff" (just go full power straight ahead) or something.
No (female) pig cares about it / No sow cares about it
But none of them is an exact match as there's no perfect overlap for all situations to which "zero fucks given" can be applied. Which isn't too surprising as most idioms and even most words don't map 1-to-1 between languages even when they share a common root.
