Get the Wait. What? mug.
A phrase used to back the conversation up when you realize you weren't listening. You caught the ice cream end of the conversation,and oops, you wish you had heard the meat and potatoes. It could be important, so you use this phrase to try and sneak by the fact that you were thinking about dirty pics and bacon cheeseburgers while your friend was pouring their heart out. Hopefully they're so distraught they'll rewind and repeat without noticing.
