O&NE
O&NE means you're old and still sharp, like a grandpa who can cuss you out and still beat you at Mario Kart.
My grandpa said, 'You think you're tough? I’ve been cussing you out since you were in diapers.'
He beat me at Mario Kart and then said, 'You’re not even trying.'
He told me I was 'as smart as a bag of chips' and then asked me why I didn’t just take the chips.
