I J and you're on the O - You’re stuck outside the joke. Used when someone is too dumb

You’re stuck outside the joke. Used when someone is too dumb to understand the joke and you're too lazy to help them.

You: What's going on? Me: I J and you're on the O. You: What's that mean? Me: You're dumb.

I J and you're on the O. You said, 'I'm not dumb.' I said, 'Yes, you are.'

I J and you're on the O. You looked confused. I said, 'You're the dumbest person I know.'
