I don't give three fucks
They don’t even care enough to throw a single fuck at your nonsense. Two might show up if they feel like it.
'You’re telling me you’re still mad about that pizza incident from 2017? I don’t give three fucks.'
'My dog just ate my homework. I don’t give three fucks about your drama.'
'You’re still crying about that one time you got passed over for a promotion? I don’t give three fucks.'
