The tooth fairy's evil sister. She visits people sleeping in the middle of the night and gives them horrible morning breath.

spitty mouth 

The sensation one feels when their mouth begins to salivate and fill with spit, after having had too much to drink. This is then usually followed by vomiting, however some can fight it off. Either way, you'll be spittin'.
