“Cold shoulder” originally meant cold cuts of meat—not literally a person’s shoulder—but there’s a popular cannibal joke:
   
“What did the cannibal get when he was late for dinner? The cold shoulder.”
 
The joke has been cited in print since at least 1992.
 
     
Wikipedia: Cold shoulder
“Cold shoulder” is a phrase used to express dismissal or the act of disregarding someone. Its origin is attributed to both 19th-century literary works and as a result of folk etymology.
(...)
Another explanation is that the phrase stems from a particular way to serve food to an unwanted guest. In this case, “cold shoulder” refers to serving of an inferior cut of meat, namely a “cold shoulder of mutton” to an uninvited guest, as opposed to serving a hot meal or roast that was fresh out of the oven to an invitee, which was customary at the time. This acted as both a direct and subtle means to let the guest know that he or she was or had become unwelcome, and had extended his or her stay.
