pig in the python
n.— «As a DRI hire, I am part of the group of State employees that has come to be called “the pig in the python.” Prior to us (us being the pig), there were years of chronic under-staffing (the python), with some years having officer intake of just 80 people, and even some years when nobody was hired.» —“Joining the Foreign Service: Re: DS Budget Help” by FSO Mexico Tales from a Small Planet Message Boards Jan. 11, 2007.
