I don't give a fig
I don't care if you're crying, laughing, or screaming. I still won't help you.
You cried about your failed science test. I said, 'I don't give a fig.'
You laughed so hard you fell off the couch. I said, 'I don't give a fig.'
You screamed at me for eating your last cookie. I said, 'I don't give a fig.'
