Breaking the fifth wall 

When after an evening of Facebooking between someone and you in the same house, they break the fifth wall and come and talk to you in person.

Worse if they talk to you about things on Facebook

Oh God, No, I can hear them getting up at the same time....we're going to go into the hallway together...can I..stall? shit, too late!

Urban Dictionary told me that the "Example should include the word "Breaking the fifth wall"" and I'm fine with that.
