I don't give a holy fuck
A phrase that's like saying 'I don't give a fuck' but with a little religion and a lot of attitude. It's used when someone is being too loud, too proud, or just too annoying.
'I don't give a holy fuck if you're the loudest kid in class, I'm still the loudest kid when I'm eating.'
'I don't give a holy fuck if you're the most proud kid in the school, I'm still the most proud kid when I'm eating.'
'I don't give a holy fuck if you're the most annoying kid in the world, I'm still the most snacky kid in the world.'
