An ugly pussy.

Often times Poodles will develop a wet, brown or rust colored area around the edges of their mouths that is visually unappealing. A vagina that is similarly aesthetically unfortunate is said to be, "A Poodle's Mouth". This can also connote an associated fragrance.
"I over comitted, and when I realized the trouble I was in, I had to work the 'ol Poodle's mouth with my thumb while pretending to eat it."
