nah see ya - A way to say you're done, you're leaving, and you don't care

A way to say you're done, you're leaving, and you don't care if they cry. It’s like giving your boss the finger and walking out with your lunch.

Boss: 'Can we have a chat?' Me: 'Nah see ya.'

Friend: 'Let’s go to the movies!' Me: 'Nah see ya.'

Teacher: 'You're failing!' Me: 'Nah see ya.'
