I don’t wanna, I don’t haveta, I ain’t gonna
The last ditch effort of a person who has no ambition. It’s what you say when you’re too lazy to try and someone else is too pushy to let you be lazy.
'I don’t wanna do it. I’m not even a little bit interested.'
'I don’t haveta go. I’ll just stay here and be boring.'
'I ain’t gonna get up. I’m going to sleep and I’m not coming back.'
