Tequila Mouth is the taste you wake up with after a night of downing tequila shots. No only is Tequila Mouth unpleasant in it's taste, but Tequila Mouth also leaves your voice raspy.
Frank: " Dude, I have Tequila Mouth to the max."
Perry: "Don't talk in my face. Your breath smells like you found a diaper on the beach and ate it."
