Breath that is so horrible it will melt your face if you are close enough. If this condition is bad enough the person shall then be known as the dragon master.
Damn as soon as Mikegot in the van his dragon breath consumed me!
When someones breath smells so bad, it's like hot, burning garbage. When you can't stand to talk to, sit next to, or even be around someone because their breath smells like a big dog just took a dump in their mouth.
