How do you...? You just...!
When relating to the way teenagers explain the method behind achieving a certain required end goal, the good doctors have taken to using the following format:
Dr 1: "How do you create a wiki?"
Dr 2: "You just create a wiki!"
This saying arose from a discussion on Snapchat on October 17, 2014, where the Doctors asked how one could set up Snapchat on their phones, to receive the answer from one of the production team that you "Just get Snapchat".
