The taste in your mouth when you wake up if you neglect to brush your teeth the previous night/day. Usually occurs from a night of heavy alcohol consumption. It can also have the feel and density of overly-sweetened honey.
Drinker 1: Man I have this horrible taste in my mouth.
Drinker 2: Dude you drank a lot last night and just passed out on the couch. You've got cat shit in the mouth.
