Pack it in
A hillbilly way to tell someone to shut their face and give up. It’s like telling someone to stop being a failure and go back to the farm.
Your mom said, 'Pack it in, or I'll feed you to the cows.'
Your dad yelled, 'Pack it in, or you're eating corn for a month.'
Your cousin said, 'Pack it in, or I'll tell the whole town about your bad hair.'
