When you double press the 'last button' on your TV remote control to check the last channel you were on or to see what's going on in the other show.
Person1: "Man, do you remember what we were watching? I just blanked."
Person2: "i'll check during commercial, hold on."
Person1: "No. Do it now. Last blast."
