you know what

We both know

You know what is a conversational phrase that signals the speaker is about to make a point, often one they've just decided on or realized.

It can introduce a change of mind You know what, let's just stay home, a revelation You know what, I think she's right, or mild confrontation You know what, I'm tired of your excuses.

The phrase invites attention without actually asking whether the listener knows anything—it's rhetorical staging, not a genuine question.
