when you wake up in the morning and look in the mirror to find that your face has not woken up yet.

Get the sleep face mug.
The face one has when driving home after eating too much caramel indulgence cake.

Also refers to a permanent facial condition caused by over using the popular narcotic, "Sleep".
Caramel cake was a bad choice, should have went with the molten volcano vanjmoresdf? cake instead. Now I have to drive all the way home with total sleep face.
