Someone's breath that smells like absolute shit, like they brush their teeth with shit toothpaste. Almost as if someone took a crap in their mouth.

The worst smell imaginable. A pokemon attack that ends the world in the middle of a poke battle.
Goku's secret move that he never used in dragonball z.

When a girl who just ate a really smelly meal (anything with garlic or onions, etc.) gives someone a blowjob and her breath smells so bad that the man's dick smells like the girl's breath afterwords. Other names for this condition are "Poop Penis Syndrome" or "Clam Gut Cock." The man will then not get any girls near his dick because it will smell like a stinky pussy. It is recommended that in order to avoid this disease, you wash your dick immediately after any blowjob, no matter who the girl was. She could be a carrier of DBD
