I don’t use profanities, but allow me, please, this time. “I don’t give a fuck”, “I don’t have fucks left to give”, etc., is used to utterly mean, I don’t care, right? I have found, though, another meaning for it.
“I don’t have fucks left to give” says that I am, absolutely, not going to let any stressful situation bring me worry, or take away my peace of mind. I am, still, giving a fuck about it, and will act to the best of my knowledge—and expediently—to resolve it, and bring it to closure.
Bottomline, because “I give a fuck”, “I have zero fucks left to give”. Do I make sense? 😅
