The shitty taste in your mouth you wake up with that gets left after a very long night of drinking, a combination of beer and food rotting in your mouth while you sleep.

Get the Dumpster Mouth mug.
The act of someone losing fair and square and not being able to handle that they got beat, a form of denial that plagues very competitive people. Getting your ass handed to you and thinking up the dumbest excuse there is.
