A loud refusal to be blamed for anything, especially when you're high, drunk, or both.

'I ain't going to take the blame for this mess, I was just here.'

'I ain't going to be the one who got caught, I'm hiding behind the couch.'

'I ain't going to be the one who got arrested, I'm gonna text my mom.'
