look up any word, like sex:
 
1.
It's the gynecologist, the lady doctor, the vaginatrician.

Duck refers to the shape of the speculum that is inserted into the vagina. It looks like a ducks bill.
"Damn it, I have my annual with the duck doctor."

"The who?"

"The duck doctor. You know, the gyno. That shit looks like a duck bill."
