War Mouth is a case of severe and uncontrollably horrible halitosis caused by a night of partying or some other taxing event that has compromised one's dental hygiene.
“It’s 8 AM and you’ve just awoken to the aftermath of last night’s party. You drank it all; the beer, the liquor, the strange concoction that was devised at 4 AM. That’s right, you have War Mouth and Listerine is here to help…”
