Origin:

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?"
Clean way of saying "motherfucker"
Usage in amongst K-pop fans most likely stems from entertainer Boom who used the phrase on episode 3 of 2PM's Idol Army.
Cast thought he said "motherfucker" in poor English and he stated he said "omma appa" and not a bad word.
An explicative that implies that it's denotee is both a mother and a father; which is at this point a medical impossibility. It is also used idomatically because of it's close relation to the word mothafucka. The word has gained much popularity in conjuntion with the latter: chinese dentist.
