Thirsty Rotten Carcass Breath
When ones breath smells like they've been chewing on a rotting animal carcass that had been left in the hot sun, combined this with not drinking liquids for a long period of time and you get Thirsty Rotten Carcass Breath.
I once tongue kissed this guy at a party but almost gagged because he had thirsty rotten carcass breath. He needed a drink, a mint and an orthodontist.
