A very loud and very rude way of saying I don't care and I'm probably gonna laugh at you
He tried to explain why he was late. I said, 'I don't give a hootnanny, you're still the worst.'
She told me I had to go to bed. I said, 'I don't give a hootnanny, I'm gonna stay up all night.'
He asked me to help him with his project. I said, 'I don't give a hootnanny, I'm gonna fail with or without you.'
