Chinese Mouth

The anus. As China is on the opposite side of the world, the anus is at the opposite end of the digestive system.

Jimmy started by licking Jenny's warm, wet pussy then moved south to her Chinese Mouth.

Mother Father Chinese Dentist 

Very obscure slang/substitute for swearing in frustration or anger.

Origin:
HBO television series
Mr. Show with Bob and David (1998 season 4, episode 5: It's Perfectly Understandable)
Sketch: Pallies (A Goodfellas parody, edited for television)

David Cross turns to Jay Johnston and yells (with terrible over-dubbed editing):

"Well you's can both grab one of my *books*,
you mother*father* *Chinese dentist*"
before shooting Jay in the head.

According to the Season 4 DVD commentary, years after the show ended, cast member Paul F. Thompkins had overheard someone talking on a cel phone in a bar utter the phrase "Mother Father Chinese Dentist!"
When asked if she was a fan of the show, her reply was "What?"
