Sleep Face

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.
