Is the smell of someones breath that resembles that of a fart, or in my cases, Dog Shit. The terminology orginates for the early 14th Century when Aristotle told his Plato (his teacher) that his breath smelt like a Guff.

1815–25; perh. imit.
Guff comes from the Latin word; mean to "Reek"

Gu- in latin means Dog

FF- in latin means Shit
"I can't believe i married that woman, she's got the worst guff breath i've ever encountered"
