In The Force Awakens, Han Solo complains that "some moof milker" put a compressor on the hyperdrive.". He said it in a derogatory way.
A moof is an agricultural work animal like a cow and is indigenous to the planet Cerea, whose inhabitants reject technology and live in harmony with nature. Han seems to be saying that some uneducated rural farmer made ignorant modifications to the Millennium Falcon.
But moofs and Cereans are rather obscure references. What is Han's personal experience with moofs or Cereans that would lead him to mention them so casually? Does he interact with them in another movie or book?
I found this link to starwars.wikia , which states that Han Solo interacted with Cereans in a novella published in 2009. The link shows that there IS an answer to this question. I was just hoping for something more artistic than one link. The quote was a memorable moment in the movie. Context on it would enrich this site.
