Foul breathe

To have bad breath

A slang term refering to people of Asian ancestry. The term comes from the fringe belief that Asians are the result of dragon/human interbreeding eons ago. These human/dragon hybrids (aka Asians, or simply dragons) have evolved to be impervious to lung cancer regardless of how heavily they smoke since they have dorment fire breathing genes. Also modern day human/dragon hybrids possess the ability to fly however no non-dragon has ever witnessed that feat first hand. This is the ancient Chinese secret everyone refers to.
