The unpleasant occurrence in which you pass out on your back with your mouth open--usually directly after a drinking binge--and the insides of your mouth drys out so completely that it feels as if all of your salivary glands have been cauterized shut. No amount of smacking your lips or sucking at the inside of your mouth will get them going again. You are fucked until you obtain and drink a glass of water or a dillo or something to get the film of dried saliva re-moisturized.

Welcome to hell.
