You know what you doing 

"You know what you doing" first appeared in a game for the Sega Genesis called "Zero Wing", along with the phrases All your base are belong to us and You have no chance to survive, make your time.

One uses this phrase to point out that the listener is or the listeners are capable of finishing some task.

Alexander: I'm going to call the guy, and convince him that we are right about this.
9001: You know what you doing!
Alexander: Thanks for the encouragement.
