Ronnie Oneal

To profess innocence when you are caught red handed committing a crime.

Don't be a fucking Ronnie Oneal. I saw you piss in my pint.

He's doin a Ronnie Oneal and denying everything even though she has a video of him shagging the next door neighbor.

Man just admit to stealing her knickers. Everyone saw you do it. Don't be a Ronnie Oneal.
